bug#34201: Make @setfilename optional in Texinfo files


From: Gavin Smith
Subject: bug#34201: Make @setfilename optional in Texinfo files
Date: Sun, 31 Mar 2019 14:33:38 +0100

Is there anybody who has time to look at this issue? The requirement
for a @setfilename line is an unnecessary hurdle to getting Texinfo
and Automake working together. It has been unnecessary for several
years now.

I have a copyright assignment in place for Automake with the FSF, so
all that would be needed would be for someone to have a look at this
patch and apply it for the next Automake release.
