This edit came up in the queue the other day, which I rejected as I felt it should have been a comment, and I checked, was already a comment by the editor.
LIKE 'WC[[R]S123456'
or
LIKE 'WC\[R]S123456' ESCAPE '\'
[The edit addedESCAPE '\'
.]
Should work.
A few minutes later it came up again and was approved.
Was this a valid edit? Was I wrong to reject it?
