Why do so many Lisp programs use strings instead of processing the
text in the buffer?  I think it's a bad idea, both in terms of
performance and in terms of GC pressure.

My impression is that this is due to people having habits from other
programming languages.

Also please note the with-output-to-string macro, which could help in
at least some of these situations.
