To be strict, momentarily "*" is not "wildcard support" but an alias for
"all windows". :-)

Unfortunately the mouse gets too sloppy as it stands in the final
version. Test this:
(1) Put
NoTitle { "XTerm" }
into .twmrc, start xterm, then xcalc. (I assume xcalc has titlebar.)
(2) Now move mouse into xcalc, then into xterm. How do you focus xterm?
Probably only by killing xcalc. (Or doing f.unfocus to xcalc.)
Why that?
It appears twm is architected with the "focus follows mouse" from ground
up and everywhere in the code this policy seems to be assumed (excluding
the case one executes f.focus on some window explicitly, only then you
leave the "PointerRoot" mode). Now it is true every titled window gets
focus explicitly assigned to that window (in HandleEnterNotify()), but
if you kill PointerRoot recovery in HandleLeaveNotify() no window
without a title bar is assigned focus in HandleEnterNotify(), they rely
on PointerRoot focus mode. Destroy handler (as well as f.unfocus)
recovers PointerRoot mode.
Attached is an alternative initial attempt of the sloppy-mouse
functionality. Mostly this is based on what f.focus does but adapted so
that it (1) should coexist peacefully with the PointerRoot overall
policy, (2) does not break the icon manager (keeps sending focus into
client windows if mouse is in icon manager, and so on).
This patchset is a "minimalistic implementation" in the sense that now
we don't have f.focus functionality: If one sets f.focus to some client
and then enters some other client, the focus warps over there as well.
To keep f.focus functionality probably some additional housekeeping
state is needed to distinguish SloppyFocus mode from focus tied to some
client.
There may be (I hope only) some minor cosmetic bugs in this
implementation remaining, probably in drawing icon manager entries under
some conditions.
(Apply this patchset against plain Xorg twm-1.0.3 realease.)

Why don't you use the already existing "WarpCursor" keyword for that?
There seems no apparent reason not to do that. This only is maybe a
matter of taste: to utilise existing keywords as much as possible than
inventing new ones for every feature. :-)
