Hello Юрий.

In the future, please don't open a new thread to reply to a message of a
previous thread, as this will create a new unrelated bug report in the
Automake bug tracker.  Unless, of course, you deliberately want to open
a new bug report that has originated from a previous discussion -- this
is fully legitimate.

Thank you.

That said ...

... I agree the documentation might be clearer about this.

Ralf, what about the attached patch (for 'yacc-work' and 'maint')?
Tested with "make pdf ps dvi html MAKEINFOFLAGS=--no-split".  The
output in all forms looked fine.
