[Bug-XBoard] [bug #27799] fix for nested-nested-nested variations

[anonymous]

Follow-up Comment #1, bug #27799 (project xboard):

Not sure I understand the lex syntax completely. The "+", is that a meta
character for one or more, like "*" means zero or more times, and "?" means
one or zero? And unescaped parentheses group these operators?

Btw, now that I look at parser.l, what do you think of:

(([Ww](hite)?)|([Bb](lack)?))" "([Mm]ate(s|ed)?)|([Ww][io]n(s)?.*)  {

Doesn't that match "Mateed", in stead of "Mated"?
