Fix CVE-2008-2371 (outer level option with alternatives caused crash).
The patch is from:
http://vcs.pcre.org/viewvc?revision=360&view=revision
Test case:
re:compile(<<"(?i)[\xc3\xa9\xc3\xbd]|[\xc3\xa9\xc3\xbdA]">>, [unicode]).
An option change at the start of a pattern that had top-level
alternatives could cause overwriting and/or a crash.
This potential security problem was recorded as CVE-2008-2371.
