I noticed this when I discovered the original problem. I guess ideally
Ctrl-C while a command is being executed should leave everything
unchanged. However, undo seems to work fine, so I don't think its
too much of an issue in practice. I guess one option would be to
automatically undo if Ctrl-C is detected. Someone familiar with the
undo implementation (not me) could have a shot at this (some code
near the end of do_do_join() would probably do the trick).
>we can maybe remove the check for Ctrl-C while joining lines?
Sounds a bit risky to me, and for marginal benefit.
>O(n^2) to O(n*log(n)) is certainly a major speed up.
I'll be mentioning it in my Algorithms and Data Structures subject next
semester for sure. I'm very happy to have made a (small) contribution
to a great system - thanks guys! Now, are there any instructions on how
to unsubscribe...
