Thanks.  However, your change is just this:

  === modified file 'doc/misc/Makefile.in'

   dvi: $(DVI_TARGETS)

I think at least the prerequisites should be fixed, for those several
manuals which now depend on overrides.texi to build (unless we go the
way I suggest below).

Also, overrides.texi is in the repository, but these two new rules
will overwrite it, and the modified overrides.texi could then easily
be committed by mistake as part of the next "bzr ci", thus propagating
a file with "@set WEBHACKDEVEL" to everyone else.  That's bad, I
think.

Finally, I believe there are shells out there which will not overwrite
an existing file with the ">" redirection; you need to remove the file
first.

Bottom line, I think it will be much better to remove overrides.texi
altogether, and then modify the `webhack' target as follows:

  webhack:
  	$(MAKE) all MAKEINFO_OPTS="-DWEBHACKDEVEL --force -I$(emacsdir)"

Could you see if this will do what you want?
