Okay, good to know. That means 'urxvt.bat' and 'urxvt'(#!/bin/sh) will
not conflict.  We're still left with a possible future conflect where
'rxvt.bat', 'rxvt'(#!/bin/sh), and current/old 'rxvt.exe' are all in the
same directory.  But we can worry that issue when it comes up -- which
may yet be a while.

Sure, but then I'd have to
  (1) compose a command string by explicitly concatenating all
  positional arguments into one big string.
  (2) prepend the target app
  (3) use eval (actually, in cmd.exe just '%var% causes var to be
  expanded and executed)
BUT I'd have to worry about parsing and quoting rules, preserving
embedded spaces in arguments (-fn "Lucida Console-16"), multiple
expansion issues...

Something like the following *might* work, but only if used with cmd /v
or 
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\DelayedExpansion
= 0x01
I don't know how to set delayed expansion from within a batch file...


@echo off 
set A=
if "%1" == "" goto AisPopulated 
for %%f in ( %* ) do set A=!A! %%f
:AisPopulated

REM somehow figure out how to set tgt to proper exe

set launch=%tgt% %A%
%launch%


Yes, it's possible -- but really really prone to error, bugs,
complaints, mailing list traffic. Maybe it's not as hard as I think it
will be, but IMcurrentO it's much better to simply say "use ~/.Xdefaults
and -name variants if needed".
