examples: beware of readline on macOS

Browse Source 
macOS' version of readline does not repeat stdin on stdout in
non-interactive mode, contrary to the current version of GNU readline.

* examples/test: Add support for strip_prompt.
* examples/c/bistromathic/bistromathic.test (strip_prompt): Set it
when needed.
Early exit when needed.
