undo in shell buffer?

["Samuel Wales" <samologist@gmail.com>]

I ran a large output, and found that a warning popped up about undo
using up too much memory.

Is undo necessary in that buffer except for the last line?  Is it safe
to make undo-limit buffer-local and set it to a low value?

Also, I'm not sure I know the benefits and drawbacks of shell vs.
term.  Both seem to work with a little tweaking.  Which do most people
use?

I find m-r to be inconvenient in the shell buffer, because you have to
press ret.  i also find it inconvenient that cycling the command line
history wraps around instead of stopping.  Yet perhaps I would have to
get used to things in term, like moving around to copy stuff.  And my
prompt isn't working in term yet.

Thanks.
