(This is a low-level primitive used internally by the MUQ MUF
regular expression implementation: It will not normally be of interest
to users unless they are writing another regular expression implemention
for Muq.)
Get string range matched by i-th parenpair.
Legal values for i currently range from 0 to 31.
Return value start will be offset of first character in matched string.
Return value stop will be offset of first character past
substring in matched string.
If no match is current registered, both return values will be zero.
Go to the first, previous, next, last section, table of contents.
