serious flaw of @c

[Werner LEMBERG]

Consider this innocent construction:

  @address@hidden
  }

which fails with

  Argument of @commentxxx has an extra }.

This demonstrates that address@hidden' is not the same as `%' in TeX :-(

A fix would require that for all commands which take an argument the
catcode of ^^M is changed so that it isn't prematurely converted to a
space.  Alternatively, the newline character could perhaps generally
be made active and protected with address@hidden@protect (similar to
LaTeX's inputenc mechanism) to achieve this.

Besides being a very ugly (undocumented) deficiency, a working
solution is quite important for the address@hidden' trick within macros (if
expanded with `texi2dvi -E').
