Normally we'd rely on -T, does grep not have it?

grep: add the option to show full commit hash for every result

People often would want to send the result of hg grep to someone
else with a remote repo. Currently it's of no big use since revision
ids are not global. Introducing --hash will allow people to identify
search results in a global way.
