@ftable problem

[Dmitry Sivachenko]

Hello!
I am using texinfo-4.0, with the latest texinfo.tex.
It seems that @ftable doesn't include it's elements into the @findex.
After replacing @ftable with @table + the appropriate @findex everything
works fine.

You can observe this problem with GDB manual, which includes parts of the
Readline manual (and readline manual uses @ftable).

Is it a known bug?
Is it an intended behaviour?

Thank you in advace,
Dima.
