[Automake-ng] [PATCH 0/4] deptrack: some more refactorings and simplifications

[Stefano Lattarini]

This patch series offers a small but nice simplification to the automatic
dependency tracking support, by using some capabilities specific of GNU
make (e.g., the "-include" directive, the $(dir) built-in function, etc).

The improvement offered by these patches is somewhat small, and surely a
more aggressive refactoring would bring greater advantages.  But I prefer
to proceed by small steps whenever possible.  So here we go.

I will push this series in 72 hours to 'ng/master' if there is no review
by then.  For the moment, to make it easier to try it out, I've pushed it
to the temporary branch 'ng/experimental/deptrack-refactor'

Stefano Lattarini (4):
  [ng] deptrack: increase testsuite coverage
  [ng] deptrack: refactoring for "fastdep" mode
  [ng] deptrack: simplify by assuming more GNU make semantics
  [ng] deptrack: remove obsolescent comments
