ssp - remove multiple line-feeds from output

ssp is typically used in pipelines such as
nroff -ms file1 | ssp
ssp is equivalent to the 4.2BSD cat -s command.
To remove all blank lines from a file except at beginning of file, use
rmnl (see rmnl(1)). To remove all blank lines from a file including
beginning of file, use rmnl piped to ssp, or ssp piped to rmnl.
