 If they can actually share some common functions, you can put
both handlers in the same file, and symlink one to the other.

 Or use _xfunc() to call a function from the other file (which checks
if the function you want to call is already defined, else source and
then call.)

 Or maybe put something at the global level of completions/xl, so when
that file is loaded, it makes sure completions/xm is loaded, by
checking for something that xm defines.  Then the function definitions
that stick around in RAM after things are loaded are smaller and
simpler (no _xfunc, just direct calls).

 I don't use xen, so I have no plans to write completions for xen
commands myself, but patches usually get looked at eventually when
sent in to the bash-completion mailing list.  (It receives mail from
debian bugs on the bash-completion package.)
