no validation warning on 3-letter weekdays in opening_hours

[aceman]

The validator does not produce a warning on opening_hours values containing 3-letter weekdays abbreviations and even mixed 2-letter and 3-letter intervals. Also there is no warning about the colons after weekdays.
E.g.
opening_hours=Mo-Fri: 7:00-18:00, Sat: 7:00-13:00

I get no warning.

The wiki ​http://wiki.openstreetmap.org/wiki/Key:opening_hours does not mention the 3-letter abbreviations as valid.

I know JOSM uses an external library to check the syntax. So if this is a problem in the library, please forward to the author.

If I use the validator tool linked from the wiki (​http://ypid.de/~osm/evaluation_tool/) on a string of "Mo-Fri: 7:00-18:00" it does produce warnings:
Mo-Fri <--- (Please use the abbreviation "Fr" for "fri".)
Mo-Fri: <--- (You have used the optional symbol <separator_for_readability> in the wrong place. Please check the syntax specification to see where it could be used or remove it.)

And it prettifies to "Mo-Fr 07:00-18:00" (notice the added leading 0), which is correct.

But if inputting the full string of "Mo-Fri: 7:00-18:00, Sat: 7:00-13:00" the tool is silent too, no warnings and no output.

Hi

The problem is already known upstream (see issue ​#86). I already tried to fix this but it is not that trivial. I hope I can fix this in the next ​release.

Yeah, if the string is rewritten with ; separator "Mo-Fri: 7:00-18:00; Sat: 7:00-13:00", the tool gives proper warnings. ; should be fine in this case instead of , . So it really seems a bug in parsing the , separator.
