--------------------------+-------------------------------------------------
These patches change the prompt detection/stripping and update doctests to
cause no errors with Macaulay2 1.3.1.
Improvements/fixes achieved:
- examples in Macaulay2 documentation (which include input prompts) do
not break the interaction with Sage;
- empty/whitespace/comment lines can be executed;
- multiline commands can be executed;
- stripping output prompts will not cut error messages if they occur
(e.g. the first call "help Thing" currently shows some errors in
Macaulay2).
This is done by:
- changing input and input continuation prompts;
- starting with a big line number to make all output labels of the same
width;
- making sure that only output labels and spaces are stripped from the
output.
Side effects / Remaining issues:
- "restart" command of Macaulay2 is handled separately when it is called
like "macaulay2.restart()" since we need to repeat prompt adjustments;
- this command cannot be used in the string code passed to Macaulay2,
since it will cause a lock. Since this should not cause loss of data (if
the user intentionally tried to restart Macaulay2), I think this is OK.
Correct checking of all the code for "restart" in it would involve also
checking if it is inside string constants.
These patches make tickets #7882 and #7888 unnecessary.
