Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revsets: let parents() return parents of working dir This patch makes the 'set' argument to revset function parents() optional. Like p1() and p2(), if no argument is given, returns the parent(s) of the working directory. Morally equivalent to 'p1()+p2()', as expected.
