This is good for texinfo.tex.

As a general treatment for Texinfo code, I find this removal of spaces
wrong and unexpected.  This kind of transformation may be ok for
conversion, though other possibilities could make more sense but as
a representation of the Texinfo code I find it incorrect.

In particular, the fact that
aaaaaaaaaa@c
   bbbbbbbbbbb
could be represented or converted to
aaaaaaaaaabbbbbbbbbbb
looks particularly wrong to me.  It TeX does it that way, let it be, it
is not a big issue, users can workaround it if they want, but I do not
think that this should weight on the correct representation or
conversion in other formats (and in texi2any tree in particular).
