I am an admirer of Kodaly and Bartok, who were both Hungarian
composers in (early) 20th century music, so I have been learning
Hungarian in hope of understanding their works thoroughly (and I
found it a very interesting language, which somewhat resembles
Japanese in several respects...)

By the way,

Aha!  A simple and elegant patch!  I am slightly worried since
it does not check the process group, but actually it seems to be
working very well.

However, I noticed a little bug (or, at least, a singular
behavior) just now.  The variable "inforeground" referred in the
patch will not be set true if the last command in a pipeline is
in the current shell.  Hence, though it is artificial,

	% stty erase ^H | :

has no effect since the last command is a shell builtin ":",
whereas

	% stty erase ^H | cat

will modify the tty setting since the last command is "cat".

I do not think whether the last command is in the shell or not
should be relevant in this case.  The following patch would be
better:
