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

#!/bin/sh

hg init a
cd a
cp $TESTDIR/binfile.bin .
hg add binfile.bin
hg ci -m 'add binfile.bin'

echo >> binfile.bin
hg ci -m 'change binfile.bin'

hg revert -r 0 binfile.bin
hg ci -m 'revert binfile.bin'

echo % diff -r 0 -r 1
hg diff --nodates -r 0 -r 1

echo % diff -r 0 -r 2
hg diff --nodates -r 0 -r 2

echo % diff --git -r 0 -r 1
hg diff --git -r 0 -r 1
