I've committed an update which makes the -n flag control both
bordwalk() calls; it also fixes the error handling.

AFAICT, the remaining issues for r.proj are:

1. Whether to forward-project the entire input map in order to
determine the boundaries of the output map. This code is currently
present (in main.c) but disabled.

2. Whether the sense of the "-n" switch is correct, i.e. whether
cropping should be on or off by default.

3. Whether an all-null output map should really be a fatal error. 
While this may seem like a good idea for "typical" interactive use,
special-case behaviour such as this is usually a bad idea for a
"module" of a larger system.
