log: allow patterns with -f It's not uncommon for a user to want to run log with a pattern or directory name on the history of their current commit. Currently we prevent that, but I can't think of any reason to continue blocking that. This commit removes the restriction and allows 'hg log -f <dir/pat>'

run-tests: fix test result counts with --keyword specified or skips occurring This preserves the current behavior that excludes ignored or skipped tests from the number of tests run, except when tests are ignored due to the --retest flag.
