Subject: git-submodule: Instead of using only annotated tags, use any tags.
X-Git-Tag: v1.5.3-rc0~20
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bffe71f4cd44b8050e7561b9f9245febb8b21f0a;p=git.git

git-submodule: Instead of using only annotated tags, use any tags.

Some repositories might not use/have annotated tags (for example the
ones created with git-cvsimport) and git-submodule status might fail
because git-describe might fail to find a tag.  This change allows the
status of a submodule to be described/displayed relative to lightweight
tags as well.
