Change the behavior of the "git" prefix stripping for CAT_guide so
that we don't try to strip the "git-" prefix in that case. We should
be stripping either "git" or "git-" depending on the category. This
change makes it easier to add extra "category" conditions in
subsequent commits.
Before this we'd in principle strip a "git-" prefix from a "guide" in
command-list.txt, in practice we have no such entry there. As we don't
have any entry that looks like "git-gitfoo" in command-list.txt this
changes nothing in practice, but it makes the intent of the code
clearer.
When this code was added in cfb22a02ab5 (help: use command-list.h for
common command list, 2018-05-10) the only entries in command-list.txt
that didn't begin with "git-" were "gitweb" and "gitk".
Then when the "guides" special-case was added in 1b81d8cb19d (help:
use command-list.txt for the source of guides, 2018-05-20) we had the
various "git" (not "git-") prefixed "guide" entries, which the
"CAT_guide" case handles.
