Alias autodetection in grep-read-files is broken

[Jared Finder]

I have added a cons to grep-file-aliases so that it's value is now:
(("el" . "*.el")
 ("ch" . "*.[ch]")
 ("c" . "*.c")
 ("h" . "*.h")
 ("asm" . "*.[sS]")
 ("m" . "[Mm]akefile*")
 ("l" . "[Cc]hange[Ll]og*")
 ("c++" . "*.[ch] *.[ch]pp"))

Notice that the C++ line has two aliases in it.  This gets expanded by wildcard-to-regexp into
"address@hidden] address@hidden'".  It should get expanded into
"\\`\\(?:address@hidden|address@hidden)\\'".

Please fix this.
