Otherwise, the one to the left always wins. ('starting to the left of
the other', in full.)

I think I understand why you've added this new paragraph, but I'm not
at all sure that it is the right thing to do - I think there is a
danger that it will make it more difficult for the gentle reader
later to understand how the backtracking mechanism (along with the
combinatorial rules of a few simple operators) entirely determine
which match is found. I have no replacement to offer, however.

:>l179: \u      titlecase next char
:>Not sure what 'titlecase' means, or why it is more accurate than
:>'uppercase', nor why \U was not similarly changed.
:
:Because that doesn't happen there.  "titlecase" is a Unicode notion.
:(It's somewhat misleading, since it doesn't really understand proper
:titlecasing rules in English.)  But some scripts (read: charsets)
:allegedly distinguish between these.  That's why toke.c has
:toUPPER_LC_uni for uc(), but toTITLE_LC_uni for ucfirst().

I think that's worth expanding on then: taking myself as the
epitome of the man on the Clapham omnibus, the reader will not
know what this word means until it is explained.
