Eli, sorry for double-posting so quickly.
But one example where emacs doesn't work as well as bash is emacs can
get confused over what directory you are in.
For example, if you have a bash alias that switches directory, emacs
cannot monitor it.
Then it will not know how to complete.
So that makes you hesitant to write little bash scripts that change
around your directory, because you know emacs will never track them.
I think term potentially can overcome that limitation, so we'll try it
out and see, although i can imagine that it may be confusing to switch
from Control-X to Control-C.
