default strings.


* libgroff/string.cc (search): Small fix to test against NULL
pointer.


* troff/node.cc (copy): The characters in a bracket escape (e.g.,
b'abc') were stacked in reverse order when processed in a
diversion.

* troff/node.h: Added `*last' to struct `node' to make the above
fix work.

The default scale for the 'f' and 't' graphics functions were 'm'
rather than 'u' (i.e., no scaling).

defining include paths.
