The ? meta-character is used for matching zero or one occurence of the
preceding character , in this case , l .
T'his means that you'll match all words that begin with 'Wi' and continue
with one or zero 'l' .
More than that, it'll match any string in which a capital 'W' is followed
by a lowercase 'i'. For example:
"Don't you love Wile E. Coyote?"
"I'm Wigging Out."
"The password is 'KiWi'."
"The password is '123Wiked'."
