Fix "singleton" function used by regcomp() to turn character set matches into exact character matches if a character set has exactly one element. The underlying cset representation is complex; most critically it records"small" characters (codepoint less than either 128 or 256 depending on locale) in a bit vector, and "wide" characters in a secondary array. Unfortunately the "singleton" function uses to identify singleton sets treated a cset as a singleton if either the "small" or the "wide" sets had exactly one element (it would then ignore the other set). The easiest way to demonstrate this bug: $ export LANG=C.UTF-8 $ echo 'a' | grep '[abà]' It should match (and print "a") but instead it doesn't match because the single accented character in the set is misinterpreted as a singleton.
