formatted GNUmakefile

[Werner LEMBERG]

Folks,


I'm quite allergic to overly long lines in any kind of documents.
Particularly the various Makefiles have become unreadable IMHO, so I
suggest something similar to the attached version of the top-level
`GNUmakefile.in'.  What do you think?


     Werner


PS: If you want to compare with the original version, I suggest to use
    the `ediff-files' command in Emacs.
