I makes no difference - they will both work. Mine doesn't care where
the first word starts because it doesn't use ^, and yours doesn't
care where the first word starts because it's got ^ followed by \W*.
Your overall match will end up with leading spaces, mine will end up
with trailing spaces - the subsequent trim fixes them both. I like
mine because it has 1 less char ;^)
Ultimately, if it works for you, great!
