You want something along the lines of

	compctl -Tx 'W[0,remote_*] p[1,-1]' -k sshhosts

Which says that if the word in command position matches the pattern
"remote_*" and you are completing in any of the argument positions, then
use the array sshhosts.  Otherwise (part of the definition of -T, but
see below) fall through to normal completion for the command.

You can change the range specified with p[] to change where sshhosts is
used, add other extended-completion patterns, etc.  Note that you get only
one compctl -T, so if you have other commands that you want to pattern-
match in this way, you have to add more `W[0,...]' alternatives to the -x
set, e.g.

	compctl -Tx 'W[0,remote_*] p[1,-1]' -k sshhosts \
		-   'W[0,x*] c[-1,-display]' -k x11displays

and so on.

In 3.1.9 (and at some point after 3.1.5, but I forget exactly when) you
need to append `-tn' to the end of the compctl to specify the fallthrough
behavior (the default changed).
