Subject: fix detection of relative location information

an empty line number does not indicate relative loc info - it may be the
result of -no-ui-lines.
instead, an empty file name does indicate it - no file name at all makes
no sense, so this means a previous messages has set it already. and we
need this additional detection, as the entire ts file may have no line
number info to base the decision on at all.
