The part you removed adds line breaks when the string is not empty. I think you need to replace this:
($F{callAlphaStart}.equals("")
with something like this:
(($F{callAlphaStart}.equals("") or $F{callAlphaStart}.endsWith("-"))

I'm not totally sure of the syntax--maybe "||" instead of "or", maybe more parentheses, but I'm pretty sure that's the direction you need to go.
