tag: warn users about tag/branch possible name conflicts

As reported recently, Mercurial users can easily find confusion when
using a common name for a tag and a branch. It seems reasonable to warn
them about this potential outcome, to avoid that "surprise".
* Explain briefly the issue in "hg help tag"
* Warn when tagging a revision
