Subject: revision: use die_for_incompatible_opt3() for - -graph/--reverse/--walk-reflogs
X-Git-Tag: v2.43.1~23^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fa518aef564a24649ee6d8bbb29ed9c183a4b7c5;p=thirdparty%2Fgit.git

revision: use die_for_incompatible_opt3() for - -graph/--reverse/--walk-reflogs

The revision option --reverse is incompatible with --walk-reflogs and
--graph is incompatible with both --reverse and --walk-reflogs.  So they
are all incompatible with each other.

Use the function for checking three mutually incompatible options,
die_for_incompatible_opt3(), to perform this check in one place and
without repetition.  This is shorter and clearer.
