#     mailmap: remove the "repo-abbrev" comment
#     
#     Remove the magical "repo-abbrev" comment added when this file was
#     introduced in e0ab1ec9fcd3 ([PATCH] add .mailmap for proper
#     git-shortlog output, 2007-02-14).
#     
#     It's been an undocumented feature of git-shortlog(1), originally added
#     to git for Linus's use. Since then he's no longer using it[1], and
#     I've removed the feature in git.git's 4e168333a87 (shortlog: remove
#     unused(?) "repo-abbrev" feature, 2021-01-12). It's on the "master"
#     branch, but not yet in a release version.
#     
#     Let's also remove it from linux.git, both as a heads-up to any
#     potential users of it in linux.git whose use would be broken sooner
#     than later by git itself, and because it'll eventually be entirely
#     redundant.
