If we already have a strbuf, then using write_file_buf is a

your NULs), and it's more efficient (no extra formatting
step).

We use write_file_gently() to do this job currently.
However, if we see an error, we simply complain via
error_errno() and then end up exiting with an error code.
By switching to the non-gentle form, the function will die
for us, with a better error. It is more specific about which
syscall caused the error, and that mentions the
actual filename we're trying to write.
Our exit code for the error case does switch from "1" to
"128", but that's OK; it wasn't a meaningful documented code
(and in fact it was odd that it was a different exit code
than most other error conditions).

Since 9830534 (config --global --edit: create a template
file if needed, 2014-07-25), an edit of the global config
file will try to open() it with O_EXCL, and wants to handle
three cases:
1. We succeeded; the user has no config file, and we
should fill in the default template.
2. We got EEXIST; they have a file already, proceed as usual.
3. We got another error; we should complain.
However, the check for case 1 does "if (fd)", which will
generally _always_ be true (except for the oddball case that
somehow our stdin got closed and opening really did give us
a new descriptor 0).
So in the EEXIST case, we tried to write the default config
anyway! Fortunately, this turns out to be a noop, since we
just end up writing to and closing "-1", which does nothing.
But in case 3, we would fail to notice any other errors, and
just silently continue (given that we don't actually notice
write errors for the template either, it's probably not that
big a deal; we're about to spawn the editor, so it would
notice any problems. But the code is clearly _trying_ to hit
cover this case and failing).
We can fix it easily by using "fd >= 0" for case 1.

For the record, this output is not perfect. A single giant ref can
push all refs very far to the right and likely be wrapped around. We
may have a few options:
- exclude these long lines smarter
- break the line after "->", exclude it from column width calculation

This reverts commit 4d5520053 (grep: make it clear i-t-a entries are
ignored, 2015-12-27) and adds an alternative fix to maintain the -L
--cached behavior.
4d5520053 caused 'git grep' to no longer find matches in new files in
the working tree where the corresponding index entry had the "intent to
add" bit set, despite the fact that these files are tracked.
The content in the index of a file for which the "intent to add" bit is
set is considered indeterminate and not empty. For most grep queries we
want these to behave the same, however for -L --cached (files without a
match) we don't want to respond positively for "intent to add" files as
their contents are indeterminate. This is in contrast to files with
empty contents in the index (no lines implies no matches for any grep
query expression) which should be reported in the output of a grep -L
--cached invocation.
Add tests to cover this case and a few related cases which previously
lacked coverage.

We just taught the relevant functions to respect the diffopt.file field,

Technically, we do not need to avoid that call in a builtin: we assume
that builtins (as opposed to library functions) are stand-alone programs
that may do with their (global) state. Yet, we want to be able to reuse
that code in properly lib-ified code, e.g. when converting scripts into
builtins.
Further, while we did not *have* to touch the cmd_show() and cmd_cherry()
code paths (because they do not want to write anywhere but stdout as of
yet), it just makes sense to be consistent, making it easier and safer to
move the code later.

The --color=auto handling is done by seeing if file descriptor 1
(the standard output) is connected to a terminal. format-patch
used freopen() to reuse the standard output stream even when sending
its output to an on-disk file, and this check is appropriate.
In the next step, however, we will stop reusing "FILE *stdout", and
instead start using arbitrary file descriptor obtained by doing an
fopen(3) ourselves. The check --color=auto does will become useless,
as we no longer are writing to the standard output stream.
But then, we do not need to guess to begin with. As argued in the commit
message of 7787570c (format-patch: ignore ui.color, 2011-09-13), we do not
allow the ui.color setting to affect format-patch's output. The only time,
therefore, that we allow color sequences to be written to the output files
is when the user specified the --color=always command-line option explicitly.

We are about to teach the log-tree machinery to reuse the diffopt.file
field to output to a file stream other than stdout, in line with the
diff machinery already writing to diffopt.file.
However, we might want to write something after the diff in
log_tree_commit() (e.g. with the --show-linear-break option), therefore
we must not let the diff machinery close the file (as per
diffopt.close_file.
This means that log_tree_commit() itself must override the
diffopt.close_file flag and close the file, and if log_tree_commit() is
called in a loop, the caller is responsible to do the same.
Note: format-patch has an `--output-directory` option. Due to the fact
that format-patch's options are parsed first, and that the parse-options
machinery accepts uniquely abbreviated options, the diff options
`--output` (and `-o`) are shadowed. Therefore close_file is not set to 1
so that cmd_format_patch() does *not* need to handle the close_file flag
differently, even if it calls log_tree_commit() in a loop.
