Many interactive programs in unix use CR and BS characters in their
output to try to update a single line of output (e.g., in progress
indicators).

It's probably safe to do so, since probably nobody tries to do such
`carriage motion tricks' in elisp.

However ielm is a very atypical use of comint, and
`comint-carriage-motion' should definitely be turned on by default.  It
doesn't work to `turn it on for specific applications' because it's
almost always the case that you really have no idea what application in
a subprocess is going to be producing the output (e.g., if the program
directly invoked by comint is a shell, the output comes from whatever
the user invokes).
