 ;;first line of output from @2.

+;;@0 is intended to be a portable method for getting one-line results
+;;from programs like @code{pwd}, @code{whoami}, @code{hostname},
+;;@code{which}, @code{identify}, and @code{cksum}.  Its behavior when
+;;called with programs which generate lots of output is unspecified.
