I wouldn't use _values just for that feature. Try passing -F words (or
-F line if using _arguments) to compadd.

It is ignoring the contents of the $words array so you can manipulate
that (plus $CURRENT) to only cover the final arguments. Actually,
it is probably using $words[2,-1]. You can use two colons after the
asterisk in the _arguments spec to strip down the words array:

   '*::repo:_github_repos_for'

You may be better off with '*:::repo:= _github_repos_for' actually.
Depends how many normal arguments there are. That sets $words to
only those covered by this spec and then the = makes it add a fake
one for the command-position.
