Good, that's also the solution Raja likes most.

Good too.  Thanks for the quick responses.  And I do agree one such
quadrigraph is certainly extremely useful (yet to output quadrigraphs
for instance... @<@""@:@ => @<:@).

I have another question though.

I implemented a QnD --normalize in autom4te because it was too hot
trying to build M4's test suite without a quick solution to preserve
multiple empty lines.

This solution is very dirty, as it was very quick :)

Typically, one can observe that the Autotest snippet contain useless
multiple empty lines, which are to be killed, while those in the test
values have to be kept.

So I would like to remove that --normalize, completely replaced with
@""@.  Does it sound OK to everybody?
