+# Test if $1 has glob qualifiers.  This is partly magic, partly guesswork,
+# wholly flakey.
+#
+# If $2 is "complete" test if the qualifiers are complete (up to the ")"
+# at the end of the word), else that they are incomplete.
+# Sets match, mbegin, mend to reflect their location.
+# $match[1] is everything up to the start of the qualifiers themselves;
+#   this may therefore end in "(" or "(#q".
+# $match[2] is everything at the start not counting the "(" or "(#q".
+# $match[5] is the set of qualifiers themselves, not including a trailing
+#   parenthesis.
