Typo in wp-admin.css

[TobiasBg]

[20272] introduced a small typo into wp-admin.dev.css, in line 3378 (​here) (.colunms-1 instead of .columns-1).
Grepping showed that this is the only occurance of this typo in WP Core.

As noboby seems to have noticed this so far (by noticing the maybe-wrong margins that this CSS declaration changes), I assume that this declaration belongs to the "old structural css" that azaozz mentions ​here in #21042.

As this is such a trivial change, I didn't create a patch, so if someone feels like doing it...

Confirming that this is the only instance of this typo in trunk, but resolving the typo anyway.

Yes, this is a left-over, as far as I can see this shouldn't be there. Seems I missed it because of the typo :)
