Maybe wrong would be a better term for you ?
\s* means to grab any WS at the current position (including the case where
there is none).
\s*? means 0 or 1 of the above which is totally meaningless - you've already
eaten all the WS with the \s*, so in my opinion the ? is redundant to
what you have already done.
