Kai, very nice. I had something similar to your second version, but I
like the addition with the line numbering. That one is going into my
emacs library today!
You just gotta love eshell. Although I've not done it, I've heard
there is even some out there who are using eshell as their default
loging shell on their linux boxes. Sometime, when I'm a bit bored, I
might even start looking at that myself...
Then again, with emacs and elisp, when do you get the chance to get
bored!
Tim
