And now I've hit myself with a quoted version number in a .maintscript that got ~ and + escaped by debhelper 10:
'20100216+1~' ==> '20100216\+1\~' single quotes and backslash escaping is too much ... after unquoting: 20100216+1~ ==> 20100216\+1\~ See #881990, nvidia-kernel-common 20151021+5. Andreas
