regcomp.sym Update and improve descriptions of some nodes
EXACTFU nodes always now fold their strings; the information here had
not been updated to reflect that change.
And the descriptions of several EXACTish nodes are now changed to be
slightly shorter and to remove mention of the string length, which is
problematic, and is covered in the description for EXACT
