fermata on dotted notes on the top line

[Richard Shann]

I don't know if this is the right forum for posting unfortunate examples
of LilyPond's output but I came across this one:

\version "2.16"
\score {
 f''4.\fermata
}

The fermata seems connected visually with the dot on the note, it looks
better to me dragged further away, which I have done for the score in
question using Denemo.

Just in case anyone has a ready answer to my email earlier      (LilyPond
grace note synchronization feature) but assumes someone else has
answered it, I would very much appreciate guidance on it ...
