Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
fileset: add revs(revs, fileset) to evaluate set in working directory Unlike other functions, "revs()" does not select files but switches the evaluation context. This allow to match file with property in another revision that the one currently evaluated. This changeset is based on work from Yuya Nishihara.
