Not a big deal but I noticed that nested @ignore does not work with
texi2any, although it does work with texinfo.tex. For example:
@ignore
@titlepage
@title Texinfo
@subtitle The GNU Documentation Format
@subtitle for Texinfo version @value{VERSION}, @value{UPDATED}

With texi2any there are errors:
texinfo.texi:93: unmatched `@end titlepage'
texinfo.texi:94: unmatched `@end ignore'
However, it processes as expected with texinfo.tex.
I don't have a strong preference as to whether nested @ignore should
work or not but it should be consistent between the two processors.
I think we should take whichever is the easiest to implement.
In texinfo.tex, @ignore is implemented in exactly the same way
as ignored conditionals, such as @ifxml, which do nest (at least
in part - I haven't thoroughly tested different combinations).
However, if it would be any effort at all to change texi2any then
I expect it would be straightforward to change texinfo.tex to terminate
the @ignore at the first "@end ignore" encountered.
