Do not disable non-matched revset revisions
Created originally on Bitbucket by bels (Stephen Belknap)
Per the comments in this thread (http://groups.google.com/group/thg-dev/browse_thread/thread/243debd80a416b3a#), it would be better to have non-incoming revisions enabled instead of disabled.
The UI can still color the non-incoming revisions differently (even mimicking a disabled look & feel), but they should still be selectable so users can look at the diffs etc.
I don't know what actions on those non-incoming revisions may be bad, so some interactions may need to be prevented; but at the very least their diffs should be visible.
