Subject: Determine latest tag using git describe.
X-Git-Tag: mutt-1-9-3-rel~13
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=80d06b0cccc42571503fe0ab94c61ef267fc3c63;p=mutt

Determine latest tag using git describe.

Commit 8648db83 relies on `sort -V` which is unavailable on some
platforms.  Instead just use `git describe` with --abbrev=0 to only
output the tag.  We still manually compute the distance to avoid the
problem mentioned in that commit.

Additionally, add Vincent's fix from commit 3b142cea to the stable
branch.
