[PATCH] Rename misleading argument name in doerror of buff.c

[Ben Hyde <bh...@gensym.com>]

The second argument to doerror within buff.c is not an err, but rather the
direction the I/O what trying to proceeding in.  Rename it to direction so
others don't suffer.  Meanwhile rearrange some code - it's what I do.
