Attached is the updated version of the patch, which matches 

on words as opposed to lines, which means that all of the
following work in psql:

\d foo \d bar
\d foo; \d bar
\d foo \d bar;;
\d foo; <space>


This one also uses "true and false" and strips semicolons
for the following backslash commands: \C \c \d \e \i \o \s \z
