What are the advantages and disadvantages of using
	.if \w'\\$1' ...
instead of
	.if !'\\$1'' ...
in DWB 2.0 DiTroff macros?  Although the latter seems more readable, I've
seen the former used enough times to wonder about it.  I apologize for the
trivial nature of this question, but I want my macros to be as robust as
possible.  You TROFF wizards might offer your E-mail address if you object
to this posting (it's much too low-level to be covered in any references I
know of).
