This only works if the other output is interspersed "at word level",
i.e. you don't have characters from one Make mixed up with those of
another inside a single word.  Right?

Why do we need to use $(shell) at all?  Can't we use $(wildcard) to
the same effect without starting another process?  If the problem is
that some *.texi files are generated, and we don't want them in the
list, how about generating them in a subdirectory of doc/misc/?
