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.
