  just noticed in "man git-tag":

  1)  "-a" explicitly claims to create an unsigned tag
  2)  both "-s" and "-u" both claim to create signed tags

should that mean that it should be an error to try to use "-a" in combination with either of "-u" or "-s"? the synopsis does suggest that you can use only one of those at a time:

  git tag [-a | -s | -u <keyid>] ...

but i tested with (from memory) using both "-a" and "-s", and tag actually tried to do it, but failed simply because i had no key. clearly, though, it was making the attempt.

  can someone clarify this?

I think the documentation could be a little more clear. "-a" just asks to create a tag object, rather than a "lightweight" tag. Using "-s" asks for a signature, which requires having a tag object, and thus implies "-a".

So there's no point in using the two together (since "-s" already implies "-a"), but it also doesn't hurt to do so.
