Comment:
Here is version 3 of the patch. This implements Leif's idea about
./sage/.sagerc, in a simple-minded way. It also checks for the
environment variable `SAGE_SHPROMPT`.
My opinion is that the prompt for the Sage shell should indicate '''very
clearly''' that this is a Sage shell, so the default in this patch is for
it to start with "(sage-sh)" in reverse video. If you don't like it, you
can override it by setting `PS1` in .sagerc or by setting `SAGE_SHPROMPT`
anywhere.
This also doesn't print any warning message or even set the prompt if
`sage -sh` is followed by more arguments. I'm not sure I'm happy about
that, in particular the potential lack of a different prompt.
