Mopidy-MPD retains line feeds in tags in MPD response

[ohrenkram]

When an audio file contains a line feed (hex 0a) in a tag this is retained in the MPD response for this file which is then correctly identified as an invalid response by clients.

The example below is for a FLAC file containing a line feed in the Title tag, between "Presto ma non assai -" and "Tempo I".
MPD response extracted from mopidy debug log:

I realise that the FLAC file should not contain this line feed in the first place, however it would be helpful and good practice if mopidy could compensate this problem by removing the line feed before constructing the MPD response.

Environment:
Raspberry Pi 3
Raspbian GNU/Linux 10 (buster)
mopidy 3.1.1
ncmpcpp 0.9.2

My apologies - this issue should have been raised in mopidy-mpd, not mopidy. Can it be transferred?
mopidy-mpd issue 7 is related (but limited to comments tags, so this is not a duplicate).
