Indeed, it probably shouldn't with the end terminator included, since the 
period would have to be the last character.  Trying <FilesMatch 
"\.(?!login)"> would probably do it though, as it would match any file that 
has a period not followed by "login".  I have to imagine that if Apache 
recognizes a negative lookbehind, it would recognize a negative lookahead, 
since the latter is older and more established.  In any event, if the first 
suggestion worked, then that should be sufficient for finding all files that 
do not end with "login".  I'm glad to hear that Apache's regex engine is so 
advanced.
