The "[ ]" right before the \/ token is actually unnecessary--the ".*"
is sufficient given what's after the \/ token--but it makes the intent
clearer (and it should be ever so slightly faster, I think).
Thank you. I have been wondering this for almost two years. I never could
understand why the expression right before the `\/' was ever being
used. To my mind it made things muddier, not simpler: the steps taken
on the right to overcome explicitly the "left-handed greediness" that
is default behavior seemed to me to be clear and quite enough. But
now I (think I) understand that the extra expression has been used as
a form of "coder's documentation."
