texi2any --docbook currently does not work on some manuals.
Here is an input file (cut down from the libc manual) producing
the error:

The error is due to the @titlefont command.
The following fixes the error:

This code was changed in this commit:
commit 6ad7393ed21dc4ce27d9c97e0bc80a65d7a5c2a6

Use contents instead of args for brace commands in Texinfo tree
However, then there is a further error:
Not a HASH reference at ../tta/perl//../perl/Texinfo/Convert/DocBook.pm line
730.
This error is for the _convert_argument_and_end_line function. I haven't
tried to fix it.
I suspect that the DocBook code wasn't updated correctly for
whatever change was made in the commit on 2024-11-11.
