I have a consistently appearing extra line happening when line text
ends right at the end of the line, and groff inserts a newline, and where
I happen to insert a newline, I end of with two blank lines.
I am wondering how I might check for this ?
I note the hp register as provided by Werner in a previous post, and I am
sure I can get a read on the hp of my current line length and a little math
and Ive got a trap that I can call upon to determine whether the last line
has triggered a new line, in which case hp will be near 0 or the page offset.
Hmmmm .....
Seems to me there is a better and easier way to do this.
