awk '{printf />/?((NR>1)?RS:x)"%s"RS:"%s",$0}END{print x}' infile

Dude, you're true, but i like to see your skill in action, that's why i challenged you Smilie

colcrt(1)						      General Commands Manual							 colcrt(1)

NAME
colcrt - Filters text processor output for screen previewing SYNOPSIS
colcrt [- -2] [file...] The colcrt command filters output from text processors such as nroff so that it can be previewed on a cathode ray tube (CRT). OPTIONS
Suppresses underlining; this is useful for previewing boxed tables from tbl. Causes all half-lines to be printed, effectively doublespac- ing the output. This is useful when printing output with subscripts and superscripts on a line printer, where half-lines do not normally appear. DESCRIPTION
The colcrt command provides virtual half-linefeed and reverse linefeed sequences for terminals without such capability, and on which over- striking is destructive. The colcrt command changes underline characters to dashes and places them and half-line characters on new lines in between the normal output lines. NOTES
colcrt cannot back up more than 102 lines. General overstriking is lost; as a special case a | (vertical bar) overstruck with a - (dash) or _ (underline) becomes a + (plus sign). Lines are trimmed to 132 bytes. EXAMPLES
The following command line illustrates a typical use of colcrt: tbl exum2.n | nroff -ms | colcrt - | more SEE ALSO
Commands: col(1), deroff(1), more(1), neqn(1), nroff(1), pg(1), tbl(1), ul(1) colcrt(1)
