Sorry, I failed to ask the question I really wanted to ask...

I mean in one thread
   git tag -m 'AAA' BBB HEAD
and in another thread
   git tag | sort -g

and the question is whether the output of the git tag|sort -g command
is guaranteed to be from before the git tag -m... or from after the
git tag -m... but not "interleaved" in any way....

Cheers
