Subject: git-describe: really prefer tags only.
X-Git-Tag: v1.1.0~21
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=635d413430d5419cfd0ac18e2318cf46c1984750;p=git.git

git-describe: really prefer tags only.

Often there are references other than annotated tags under
refs/tags hierarchy that are used to "keep things just in case".
default to use annotated tags only, still leaving the option to
use any ref with --all flag.
