with -DSMALL backslashes are always treated by default, i.e., as
escapes. no '-r' option available. when as compiled without -DSMALL,
user can supply -r option to 'read' and make it process input as
"raw". i don't see anything wrong here.

as for compiling w/o -DSMALL, i can't even compile it because cd.c
includes show.h when compiled without -DSMALL and this file is missing
from src package.

i think i can add choice of compiling with/without -DSMALL as
configure option, adding, say, --enable-small option to configure
