This returns a modified version of the input string. It looks
for doctests, which start with a ">>>" prompt, and may be
continued with "..." prompts, as long as the "..." is indented
the same as the ">>>".

since, like most parsers, it is not geared towards preserving
the original source.)

This returns a modified version of the input string. It looks
for doctests, which start with a ">>>" prompt, and may be
continued with "..." prompts, as long as the "..." is indented
the same as the ">>>".
(Unfortunately we can't use the doctest module's parser,
since, like most parsers, it is not geared towards preserving
the original source.)
