cannot use 'q' in new playlist names

[barbeque-squared]

Discovered while working on #810. Reported as separate follow-up issue because while I didn't check older versions, I'm not sure if this is recent behaviour or has always been there. And even if it's recent, it's less of an issue compared to not being able to use any letter at all.

How to repro:
M -> Song -> Add Song -> To new playlist -> type q

expected result:
it adds the letter q to the playlist name

actual result:
popup about whether you want to quit USDX
