I'd prefer to see this spelled as "-a -m tag", but anyway,
this suggests to me that a request to create a light-weight tag
should be made to error out when -m is given, or automatically
promote itself to create an annotated tag, perhaps?  That is in line
with what happens when you do "git tag -F <file> tagname".

Oh, wait.

	$ git tag -d foo
        $ git rev-parse refs/tags/foo --
        fatal: bad revision 'refs/tags/foo'
        $ git tag -m msg foo
        $ git cat-file -t refs/tags/foo
        tag
        $ git cat-file tag refs/tags/foo
        object d84843c...
        type commit
        tag foo
        tagger Junio ....

        git version 2.1.0-rc0-247-g66c8a75

The output from "git blame -L'/^int cmd_tag/,/^}/' builtin/tag.c"
seems to indicate that we automatically turned annotate on when a
message is given via -m or -F since the very first version of "git
tag" that was re-implemented in C, i.e. 62e09ce9 (Make git tag a
builtin., 2007-07-20).

Your analysis starts to sound fishy.  What version of Git are you
talking about?
