Lint for and fix the three manual pages that were missing the standard
"Part of the linkgit:git[1] suite" end section.
Addresses the feedback on v1, in particular stylistic / variable
naming choices. I just went with all the suggestions.
I've added two new patches at the end to detect (and in 7/7 fix)
issues with "standard" sections like NAME, SYNOPSIS, OPTIONS etc. that
are out of order, e.g. git-mktag was one of two manual pages that
OPTIONS before DESCRIPTION. Those and a few other such oddities are
now fixed.
I've got a follow-up series to finish the work I started a while ago
of including the relevant git config variable descriptions in the
respective manual pages, e.g. now we have gc.* variables in git-gc(1),
but not in all manual pages. We'll hopefully consistently have that
everywhere soon, and this "sections in the right order" lint was very
useful to check those patches.

- Documentation/Makefile: make $(wildcard <doc deps>) a var
+ Documentation/Makefile: make doc.dep dependencies a variable again
- Refactor the wildcard we'll scan for "include" directives into a
- single INCLUDE_TARGETS_TXT variable for readability, consistency.
+ Re-introduce a variable to declare what *.txt files need to be
+ considered for the purposes of scouring files to generate a dependency
+ graph of includes.
+
+ When doc.dep was introduced in a5ae8e64cf (Fix documentation
+ dependency generation., 2005-11-07) we had such a variable called
+ TEXTFILES, but it was refactored away just a few commits after that in
+ fb612d54c1 (Documentation: fix dependency generation.,
+ 2005-11-07). I'm planning to add more wildcards here, so let's bring
+ it back.
+
+ I'm not calling it TEXTFILES because we e.g. don't consider
+ Documentation/technical/*.txt when generating the graph (they don't
+ use includes). Let's instead call it DOC_DEP_TXT.

+ Obviously all of that fits in one script, but I think for something
+ like this that's a one-off script with global variables it's much
+ harder to follow when a large part of your script is some if/else or
+ keeping/resetting of state simply to work around the script doing two
+ things instead of one.
+
+ Especially because in this case this script wants to process the file
+ as one big string, but lint-gitlink.perl wants to look at it one line
+ at a time. We could also consolidate this whole thing and
+ t/check-non-portable-shell.pl, but that one likes to join lines as
+ part of its shell parsing.
+
+ So let's just add another script, whole scaffolding is basically:
+
+ use strict;
+ use warnings;
+ sub report { ... }
+ my $code = 0;
+ while (<>) { ... }
+ exit $code;

+ We'd spend more lines effort trying to consolidate them than just
