[Quilt-dev] [PATCH] scripts: let users override LESS env variable.

[Kent R. Spillner]

Add a QUILT_LESS_ARGS variable that can be used to configure what quilt will
set LESS to when LESS is undefined.  Defaults to -FSRX so no functional change
in the default case, but allows users to drop the -F argument as needed (for
example, when using a multiline shell prompt) without explicitly setting LESS.
