Hi Akim,

The reasoning was fairly tortured :)

To document the patsubst internal change I had to invent a contrived
example so that the user could see the expansion. That example has
problems...

There are two possible solutions:

* document patsubst in the context of the user dep files patch, where
  the behavour is truly static.

* patsubst expand variables before they hit Makefile.in. (enabled by
  an option to protect people (e.g. myself) who already abuse Automake
  by passing through patsubst expressions).

>From your reaction, I suspect the second might be the better
solution. Unfortunately it is more work...

Cheers,
Alex.
