FIXME: This loses "ATTRIBUTE_UNUSED" where they existed, and also
all of the files committed here need that compiler hint added to
all of the new arguments ('canvas', 'last', etc.) since they
obviously don't use them either.
Like so --
find . -name "*.c" -or -name "*.h" -exec indent -nbfda -npcs -npsl -bli0 --no-tabs {} \;
The `indent` invocation differs from the last one noted in
CHANGES.txt (from 2006!?), in that I've added "--no-tabs",
to ensure indents are all space-based.
