[PATCH 00/12] RFC: fixits and --update

[Akim Demaille]

I felt bad for people who have to update their grammar file because of
stupid changes such as %define variable names.  This series of patches
is to free me from guilt.

The diagnostics are improved, there's a new -ffixit option to get
support from IDEs/Editors, and now the option --update updates the
grammar file with the new directives/variable names (and leaves a
backup of the original grammar file).

There should be a piece of code, and maybe we should also suggest to
use --update at the end of a run where there were fixits.

WDYT?

It's currently in the "fixits" branch.
