    GRegex: update documentation for partial matching
    
    The restrictions on partial matching no longer apply with PCRE >= 8.00.
    
    The pcrepartial manpage contains the "FORMERLY RESTRICTED PATTERNS"
    section:
    
    "For  releases  of PCRE prior to 8.00, because of the way certain
    internal optimizations were implemented in the pcre_exec() function, the
    PCRE_PARTIAL option (predecessor of PCRE_PARTIAL_SOFT) could not be used
    with all patterns. From release 8.00 onwards, the restrictions no
    longer  apply,  and  partial  matching  with  can  be requested for any
    pattern."
