pkgdev commit: use bash brace expansion when title is too long

[thesamesam]

At ::gentoo commit 5ff8c2478af6b564427e575dcc72fb198246cb80, I ran:

$ git rm -rf *1110* *117*r1*
rm 'sys-devel/gcc/gcc-15.0.0_pre20241110.ebuild'
rm 'sys-devel/gcc/gcc-15.0.0_pre20241117-r1.ebuild'
$ git rm -rf *15.0.0_pre20241117.ebuild
rm 'sys-devel/gcc/gcc-15.0.0_pre20241117.ebuild'
$ pkgdev commit
[master 44ebb36794662] sys-devel/gcc: drop versions

 delete mode 100644 sys-devel/gcc/gcc-15.0.0_pre20241117.ebuild

The commit message doesn't contain the versions because it would be too long. We could write the commit message as sys-devel/gcc: drop 15.0.0_pre20241110, 15.0.0_pre20241117{,-r1} which would fit.

Do you know a lib / code that finds such common thing and suggest shorter variant?
