    * src/regex-emacs.c (regex_compile): Remove useless condition
    
    This condition didn't have any visible effect (as ^ is not a
    repetition operator); all it did was to generate slightly worse regexp
    bytecode for out-of-place (literal) ^ in the midst of literal
    characters (bug#64128).
