Here it is, but keep in mind that I'm not really strong in writing
documentation :-(

Not sure if make-stds.texi is "our" file. It's rewritten by "wget-update"

        * Added a comment before rules for scripts.
        * doc/make-stds.texi (Makefile Basics): Mention limitations of
        suffix rules.

 Don't assume that @file{.} is in the path for command execution.  When
