Hello,
I apologize that I post a followup to my own message, but I have made a
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,
Stepan Kasal
