After thinking about this, I suggest a simpler interface for doctest mode.
Any logical line starting with a whitespace (or TAB) is ignored unless the first
non-whitespace character is a ?, which is then also ignored.

Both the source and the 'gphelp -detex' version of the GP function documentation
has the property that any GP code example has each line starting by some spaces.

So I have made a new branch 'bill-doctest_ws' that implement this variant.

Cheers,
Bill.
