Revert changeset ef1f1a4b2efb; add another test for glob: patterns
With that changeset, it's impossible to use a glob: pattern to match
e.g. all files ending in .py - glob:**.py would also match all files
in a directory called dir.py.
#!/bin/sh
hg init
hg branch dummy # needed so -r "" doesn't point to the unnamed/default branch
touch a
hg add a
hg ci -m "a" -d "1000000 0"
echo 123 > b
hg add b
hg diff --nodates
hg diff --nodates -r tip
echo foo > a
hg diff --nodates
hg diff -r ""
hg diff -r tip -r ""
true
