Re #320.
The __sane_unused__ symbol was used slightly more often then UNUSEDARG
and, more importantly, defined in include/sane/sanei_backend.h. That
makes it readily available to virtually all backends.
While reading through the SANE sources I noticed some annoying typos
in the comments. This patch is my contribution to make the SANE
sources slightly more pleasant to read.
Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
