Extend parser to accept '_' in numbers.
* NEWS: Announce change.
* lex.ll: Define NUMBER to be a NUMREAL (real number) or NUMHEX (hex number).
Define NUMREAL to begin with a digit (D) followed by more digits or an '_'.
Define NUMHEX to begin with 0[xX], a hex digit (a-fA-F0-9), followed by '_' or
more hex digits.
Define EXPON to have a digit (D) followed by more digits or an '_'.
* lex.ll (octave_base_lexer::handle_number): Strip out any underscores before
processing number with sscanf.
* parser.tst: Add tests for new behavior.
