It may be true that allowing customizable paths may be more useful than
not allowing them, so I do not have fundamental objection to this
enhancement.  However, I doubt this s/konqueror/kfmclient/ is a good idea.

As a general rule, if you allow the user to explicitly say "instead of
what you would normally use, use _this_", you should not try to outsmart
the user by using something else that you derived from that "_this_" the
user gave you.

If the user wants to use kfmclient, then the user can say so.  If the user
wants to really launch konq instead of using kfmclient for whatever
reason, the outsmarting code will interfere and make it impossible.
