Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
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.
