It's generally a good idea in all text files since it isn't obvious to
the reader it's present and may sometimes have significance. In troff,
end-of-line whitespace is significant.
$ cat -A eolspc.tr
.ds s foo $
"\*s"$
$ nroff eolspc.tr | grep .
"foo "
$
Here, GNU cat's -A option is appending `$' to the end of the lines,
showing `foo' on the first line of eolspc.tr has a trailing space. That
makes it into the definition of string `s' as can be see in the output
of nroff.
Cheers,
Ralph.
