Good point. But if I recall correctly, then Kurt (whom you may know from his
TU Wien days and who is still just a local phone call away) once told me that
Karl Berry supposedly had a fix for this.  But maybe both Kurt and I were
dreaming and this is a 'cannot be fixed'.   Which would be a pity as Debian
does allow ~ in filenames for the nice 'sorts lower than empty string' trick
that is so suitable for pre-releases.

Kurt, can you do that to the texinfo sources?

| I am not sure that this can be fixed at all ...
| 
| texinfo can set the catcode for ~ to 11 before inputting a file, but
| then it will be like that for all the input-ed file, which is NOT a good
| idea.
| 
| I will ask upstream texinfo about ideas.

Keep us posted, and thanks for all your help on libpoppler rebuilds and now
this!

Cheers from chilly Chicago,  Dirk
