[texinfo-pretest] the new @quotation command

[Karl Berry]

    consequence is that it isn't obvious to use that feature in a non english 

Yeah, I see.  How about if we add a second optional argument to specify
text that overrides the first for the output (and then the first is used
only to determine if it's a special Docbook case).  I don't think the
user should have to specify formatting, that's contrary to Texinfo's
design.

Thus, the current
@quotation Warning
would continue to work as it does, but you could write
@quotation Warning, Attention
to get a docbook <warning> tag but "Attention" in the other formats.

    (Notice the `@ ', this is yet another issue.)

In this particular case, I guess you could write
  @quotation Warning, Attention@ 
I haven't tried it.

Anyway, this is an issue for every single piece of text that Texinfo
generates.  Besides punctuation conventions, there's word order and
plenty of other language/script-specific issues that Texinfo makes no
attempt to support, when it obviously should.

Thanks,
