4933910ab7 mailinfo: handle_commit_msg() shouldn't be called after finding patchbreak
There is a strange "if (!mi->cmitmsg) return 0" at the very beginning
of handle_commit_msg(), but the condition should never trigger, because:

 * The only place cmitmsg is set to NULL is after this function sees
   a patch break, closes the FILE * to write the commit log message
   and returns 1.  This function returns non-zero only from that
   codepath.

 * The caller of this function, upon seeing a non-zero return,
   increments filter_stage, starts treating the input as patch text
   and will never call handle_commit_msg() again.

Replace it with an assert(!mi->filter_stage) to ensure the above
observation will stay to be true.

13c6df2642 mailinfo: move filter/header stage to struct mailinfo
Earlier we got rid of two function-scope static variables that kept
track of the states of helper functions by making them extra arguments
that are passed throughout the callchain.  Now we have a convenient
place to store and pass them around in the form of "struct mailinfo",
change them into two fields in the struct.

fbbcafd060 mailinfo: do not let find_boundary() touch global "line" directly
With the previous two commits, we established that the local
variable "line" in handle_body() and handle_boundary() functions
always refer to the global "line" that is used as the common and
shared "current line from the input".  They are the only callers of
the last function that refers to the global line directly, i.e.
find_boundary().  Pass "line" as a parameter to this leaf function
to complete the clean-up.  Now the only function that directly refers
to the global "line" is the caller of handle_body() at the very
beginning of this whole callchain.

69e24defd6 mailinfo: do not let handle_boundary() touch global "line" directly
This function has a single caller, and called with the global "line"
holding the multi-part boundary line the caller saw while processing
the e-mail body.  The function then goes into a loop to process each
line of the input, and fills the same global "line" variable from
the input as it needs to read more lines to process the multi-part
headers.

Let the caller explicitly pass a pointer to this global "line"
variable as an argument, and have the function itself use that
strbuf throughout, instead of referring to the global "line" itself.

There still is a helper function that this function calls that still
touches the global directly; it will be updated as the series progresses.

This does not make a difference within the context of "git mailinfo"

008ed7df93 tag.c: use the correct algorithm for the '--contains' option
In b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-09-11) we port tag.c
to use the ref-filter APIs for filtering and printing refs.  In
ref-filter we have two implementations for filtering refs when the
'--contains' option is used.

Although they do the same thing, one is optimized for filtering
branches and the other for tags (borrowed from branch.c and tag.c
respectively) and the 'filter->with_commit_tag_algo' bit decides
which algorithm must be used.  We should unify these.

When we ported tag.c to use ref-filter APIs we missed out on setting
the 'filter->with_commit_tag_algo' bit.  As reported by Jerry
Snitselaar, this causes "git tag --contains" to work way slower than
expected, fix this by setting 'filter->with_commit_tag_algo' in
tag.c before calling 'filter_refs()'.

33e8fc8740 usage: do not insist that standard input must come from a file
The synopsys text and the usage string of subcommands that read list
of things from the standard input are often shown like this:

	git gostak [--distim] < <list-of-doshes>

This is problematic in a number of ways:

 * The way to use these commands is more often to feed them the
   output from another command, not feed them from a file.

 * Manual pages outside Git, commands that operate on the data read
   from the standard input, e.g "sort", "grep", "sed", etc., are not
   described with such a "< redirection-from-file" in their synopsys
   text.  Our doing so introduces inconsistency.

 * We do not insist on where the output should go, by saying

	git gostak [--distim] < <list-of-doshes> > <output>

 * As it is our convention to enclose placeholders inside <braket>,
   the redirection operator followed by a placeholder filename
   becomes very hard to read, both in the documentation and in the
   help text.

Let's clean them all up, after making sure that the documentation
clearly describes the modes that take information from the standard
input and what kind of things are expected on the input.

63af4a8446 strbuf: make stripspace() part of strbuf
This function is also used in other builtins than stripspace, so it
makes sense to have it in a more generic place.  Since it operates
on an strbuf and the function is declared in strbuf.h, move it to
strbuf.c and add the corresponding prefix to its name, just like
other API functions in the strbuf_* family.

Also switch all current users of stripspace() to the new function
name and keep a temporary wrapper inline function for any topic
branches still using stripspace().
