Would it be possible to modify AWB so that it doesn't block when 2 typo rules have the same "find" value but different "replace" value ?
I'm not even asking that AWB use both "replace" values, just that it doesn't show an error message, and that it keeps working with the typo rules.

See discussion on AWB bugs page.

Basically, I'd like to use this possiblity to define 2 replacements for comma+2 apostrophes+whitespace: either 2 apostrophes+comma+whitespace (the apostrophes are the end of italics formatting for the word before the comma) or comma+whitespace+2 apostrophes (the apostrophes are the beginning of italics for the word after the comma).
I tried it on frwiki: it was taken into account by WPCleaner (both suggestions displayed), but it created problems for AWB.
