[Quilt-dev] [PATCH] Don't export arbitrary variables

[Jean Delvare]

Instead of exporting an arbitrary list of quilt internal variables,
which helper scripts may or may not use, let each command explicitly
export variables as needed before calling an helper script. This is
both clearer and more efficient.

In practice, only dependency-graph needs to access internal
variables at the moment, and it only uses $QUILT_PC.
