I haven't seen any complains so far and also noone has brought up evidence
yet that the memory footprint of Xprint has grown considerably compared
to the version with Xrm.c code compiled in directly.

Right, it would only make some sense if Xrm.c would not reference any
other pieces of Xlib. Certainly it could be split to do so, however
unless there is a compelling reason one should probably not go this

Actually this was an easy one to deal with - except ...
