I have no objection. Indeed, I am currently working on pcregrep (fixing
various oddities with --include and --exclude) and its code could
perhaps be made a bit tidier if this flag exists. What shall we call it?
PCRE_STUDY_NEVER_NULL? PCRE_STUDY_NONULL? PCRE_STUDY_FORCE_ALLOC? Maybe
NONULL is clearest, but I don't really mind (and maybe there's something
better).
