Martin von Zweigbergk <martinvonz@google.com> [Fri, 08 May 2020 08:50:47 -0700] rev 44808
diff: use cmdutil.check_at_most_one_arg() for checking --rev/--change
The same check was done in extdiff as well, so I fixed that too.
There are apparently no tests for this.

copy: give better error message when no source paths found with --at-rev
The new error message matches what we show when marking copies in the
working copy.
