Hello, Automake gurus.
I have a special case for bug#54063. In my case, the .texi file is
missing during 'automake' time, because it is being created by
'configure' from a matching .texi.in file. That file exists during
'automake' time, so it can be scanned for the output filename - no
need to use /dev/null in such simple case.
The attached patch (with a test) should fix this issue. Hope I've done
everything the right way.
