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"

'''share a common history between several working directories'''

"""create a new shared repository
Initialize a new repository and working directory that shares its
history with another repository.
NOTE: using rollback or extensions that destroy/modify history
(mq, rebase, etc.) can cause considerable confusion with shared
clones. In particular, if two shared clones are both updated to
the same changeset, and one of them destroys that changeset with
rollback, the other clone will suddenly stop working: all
operations will fail with "abort: working directory has unknown
parent". The only known workaround is to use debugsetparents on
the broken clone to reset it to a changeset that still exists
(e.g. tip).
