diff mercurial/commands.py @ 38427:7fbb5d76c555

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
grep: add --diff flag Adds a diff flag, which works exactly same as all, in fact since --all searches diffs, there diff is a better name for it. The all flag is still here for backward compatibility reasons. Some major tests for all has been picked and added for diff. Differential Revision: https://phab.mercurial-scm.org/D3763
