[texinfo-pretest] conditional macros problem

[Karl Berry]

    What do you think about having two macros, say, @NewMacro and
    @NewMacroWithActiveNewline to handle those issues in a clean way?

May be necessary to resort to that.  But if a macro needs both active
and normal newlines ... maybe the answer is an @newline{} (or whatever)
command which means "active newline".  Hmm.  Have to try.

    Ugly.  Why not using TeX syntax directly?

Obviously desirable for TeX.  Not desirable for makeinfo, or from the
standpoint of the Texinfo language design (such as it is), since it's a
new argument specification syntax not otherwise used.  Again, may be
necessary to resort to that, nevertheless.

Thanks for the ideas.
