Check unknown entity matching in Padatious

From sgee in Chat:

regarding

NOTE: Currently, the number of :0 words is not fully taken into consideration so the above might match quite liberally, but this will change in the future. # (lastline)

I'll guess the future is now, since i'm only able to match "..morgen um 18 Uhr.." with :0 um :0 :0 (not :0 um :0). Could/Should be removed, right?
("... tomorrow at 6 oclock .." is more natural than ".. at 6 oclock tomorrow .." - at least in geman)

Potentially one of Matthews fixes addressed this and I just missed it. Would like to test it and ensure it's working as expected.
