silly mistake:

Of course the proposed help is enough; perl captures the output of the
command, it doesn't go to a terminal.

So if were so kind to add the above change, autom4te could happily remove
the old hack, without any need for `-b'.

(The change means that
        m4 input_file | less
will now be buffered and interruptible, but I presume it's OK.)

Thank you,
