Subject: builtin/cat-file: rename variable that tracks usage
X-Git-Tag: v2.50.0-rc0~101^2~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=84a1d0039a7d9974d4900d730ba7edeef31b8e43;p=thirdparty%2Fgit.git

builtin/cat-file: rename variable that tracks usage

The usage strings for git-cat-file(1) that we pass to `parse_options()`
and `usage_msg_optf()` are stored in a variable called `usage`. This
variable shadows the declaration of `usage()`, which we'll want to use
in a subsequent commit.

Rename the variable to `builtin_catfile_usage`, which is in line with
how the variable is typically called in other builtins.
