While this may not break anything per-se, I find the name of the new
macro not quite intuitive.

The build-docdep script opens $(wildcard *.txt) itself (without
getting them fed from Makefile) to find what other files are used
via "include::", and then it recursively scans more files that are
used via "include::" to build dependencies.  Makefile assumes the
"include::" chain would pull in $(wildcard config/*.txt) files, but
this assumption may not prevent other *.txt files from getting
pulled in (not a new problem introduced by this patch).

I am not sure what these *.txt files involved in the process should
be called, but "include targets" sounds something else.  Naïvely, I
would say "we rebuild documentation dependency any time any source
text file changes", so if this were called "ALL_TXT" or something
like that, I wouldn't have such a reaction.

Thanks.
