[help-texinfo] @,{c} in @node fails although @'o etc succeeds

[Robert Dodier]

Hi Karl,

An observation -- it appears that @node is OK with accent commands
such as @'o, @'a, @'e, but @node with @,{c} (cedilla) fails.
Enclosing the offending word in { } e.g. {equa@,address@hidden doesn't help.
Including the command line argument --commands-in-node-names doesn't help.

For what it's worth the makeinfo error messages are "Misplaced {"
and "Unknown command `'".

As it happens the @,{c} is very common in Portuguese. I wonder 
what needs to be done to make @node happy with that.

As a stop-gap measure, I guess all instances of @,{c} can be 
replaced by ç -- makeinfo and texi2html seem happy with that.
I'm guessing texi2dvi doesn't like that, although I can't tell for
sure because texi2dvi is unhappy with a lot of things. :(

Thanks a lot for any information.

Robert Dodier
