Don't force '(time_diff) ago' sequence in the post revision information

[vanillalounge]

Some languages (Portuguese, for one) express this the other way around, i.e. '(string) (time_diff)'.

Example: '3 days ago' translates to 'há 3 dias' ('ago' is 'há')

Introduced in [23506].

The whole string should be translatable. The placeholders need numbers, and the string should get a context parameter explaining what they are for.

In German it would be: Vor drei Tagen (date).

[johnbillion]

Patch which adds context and a translator comment.

[SergeyBiryukov]

The same change is needed in two more places:
​http://core.trac.wordpress.org/browser/trunk/wp-admin/includes/ajax-actions.php?rev=23661#L2166
​http://core.trac.wordpress.org/browser/trunk/wp-includes/post-template.php?rev=23653#L1487

Also note the missing i18n in line 1492 in post-template.php (introduced in [23639]).

[johnbillion]

Updated the patch to add in the other missing i18n.

[SergeyBiryukov]

Looks good.

The context in line 1493 is probably not necessary, since the string seems self-explanatory and is not used anywhere else. Wouldn't hurt though, I guess.

[johnbillion]

Yeah I thought it'd be better to have it than not.

In 23743:

Fix i18n for revision diff strings displaying human time.
