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
touch a
hg add a
hg commit -m "Added a" -d "1000000 0"

touch main
hg add main
hg commit -m "Added main" -d "1000000 0"
hg checkout 0

echo Main should be gone
ls

touch side1
hg add side1
hg commit -m "Added side1" -d "1000000 0"
touch side2
hg add side2
hg commit -m "Added side2" -d "1000000 0"

hg log

echo Should have two heads, side2 and main
hg heads

echo Should show "a side1 side2"
ls

hg update --debug -C 1
echo Should only show "a main"
ls
