    regex: Require PCRE 8.31
    
    PCRE >= 8.31 is required for PCRE_INFO_MAXLOOKBEHIND usage, introduced
    in commit 6fbb1463429748bed7ab6593779430ee1c0664f5 (2013/07).
    
    regex can also make use of the PCRE_NO_AUTO_POSSESS feature from PCRE
    8.34, but this is optional and properly guarded already.
