regression: ESS cannot be compiled

[Norbert Preining]

Dear all,

down here at Debian we got another bug report about a FTBFS, which
went away when switching to an older version of texinfo.tex:

I have reduced the problematic case to the following minimal example:

\input texinfo   @c -*-texinfo-*-
@setfilename ess.info
@settitle ESS -- Emacs Speaks Statistics

@macro ESS{ARG}
@acronym{ESS\ARG\}
@end macro

@ESS{}: bad

@ESS{[R]}: good

@bye

The output is:
./bla.texi:9: Argument of @gobblespaces has an extra }.
<inserted text> 
                @par 
<to be read again> 
                   }
@doacronym address@hidden ->address@hidden @lsize #1}
                                                  @def @temp address@hidden 
@temp ...
l.1 @address@hidden }
                               @texinfoc
@scanmacro ...atspaces address@hidden address@hidden }
                                                  @aftermacro 
l.9 @ESS{}
          : bad
? 

Can anyone comment on this?

Thanks a lot

Norbert
