03bb366de4 svn: use correct variable name for short OID
The commit 9ab33150a0 ("perl: create and switch variables for hash
constants", 2020-06-22) converted each instance of the variable
$sha1_short into $oid_short in the Subversion code, since git-svn now
understands SHA-256.  However, one conversion was missed.

As a result, Perl complains about the use of this variable:

  Use of uninitialized value $sha1_short in regexp compilation at
  /usr/lib64/perl5/vendor_perl/5.30.3/Git/SVN/Log.pm line 301, <$fh>
  line 6.

Because we're parsing raw diff output here, the likelihood is very low
that we'll actually misparse the data, since the only lines we're going
to get starting with colons are the ones we're expecting.  Even if we
had a newline in a path, we'd end up with a quoted path.  Our regex is
just less strict than we'd like it to be.

However, it's obviously undesirable that our code is emitting Perl
warnings, so let's convert it to use the proper variable name.

9ab33150a0 perl: create and switch variables for hash constants
git-svn has several variables for SHA-1 constants, including short hash
values and full length hash values.  Since these are no longer SHA-1
specific, let's start them with "oid" instead of "sha1".  Add a
constant, oid_length, which is the length of the hash algorithm in use
in hex.  We use the hex version because overwhelmingly that's what's
used by git-svn.

We don't currently set oid_length based on the repository algorithm, but
we will in a future commit.

b3275838d9 pager: remove 'S' from $LESS by default
By default, Git used to set $LESS to -FRSX if $LESS was not set by
the user. The FRX flags actually make sense for Git (F and X because
sometimes the output Git pipes to less is short, and R because Git
pipes colored output). The S flag (chop long lines), on the other
hand, is not related to Git and is a matter of user preference. Git
should not decide for the user to change LESS's default.

More specifically, the S flag harms users who review untrusted code
within a pager, since a patch looking like:

    -old code;
    +new good code; [... lots of tabs ...] malicious code;

would appear identical to:

    -old code;
    +new good code;

Users who prefer the old behavior can still set the $LESS environment
variable to -FRSX explicitly, or set core.pager to 'less -S'.

The documentation in config.txt is made a bit longer to keep both an
example setting the 'S' flag (needed to recover the old behavior)
and an example showing how to unset a flag set by Git.

e54c1f2d25 pager: set LV=-c alongside LESS=FRSX
On systems with lv configured as the preferred pager (i.e.,
DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the
environment) git commands that use color show control codes instead of
color in the pager:

	$ git diff
	^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m
	^[[1mindex aa4f0b2..17e113e 100644^[[m
	^[[1m--- a/.mailfilter^[[m
	^[[1m+++ b/.mailfilter^[[m
	^[[36m@@ -1,11 +1,58 @@^[[m

"less" avoids this problem because git uses the LESS environment
variable to pass the -R option ('output ANSI color escapes in raw
form') by default.  Use the LV environment variable to pass 'lv' the
-c option ('allow ANSI escape sequences for text decoration / color')
to fix it for lv, too.

Noticed when the default value for color.ui flipped to 'auto' in
v1.8.4-rc0~36^2~1 (2013-06-10).

68868ff573 Move Git::SVN::get_tz to Git::get_tz_offset
This function has utility outside of the SVN module for any routine
that needs the equivalent of GNU strftime's %z formatting option.
Move it to the top-level Git.pm so that non-SVN modules don't need to
import the SVN module to use it.

The rename makes the purpose of the function clearer.

b74fda1c9b Extract Git::SVN::Log from git-svn.
Straight cut & paste.

Also noticed Git::SVN::Ra wasn't in the compile test.  It is now.
