If you create a filter that should deny adding special lines with e.g. "added_lines rlike 'x'" and 'x' is the content of the last line and s.b. adds some more lines at the end the filter is matching because CR/LF was added. So removed_lines contains 'x' and added lines contains 'x<LF>' I think changes only containing CR/LF should not be added to the diff because it make simply add_lines filter more complicated because you have to extend the query for checking removed_lines containing the line without LF.
Can you give an example? The AbuseFilter diff variables are built using the standard wfDiff function, which also is also used for normal diffs available from the history navigation screen. Maybe this bug needs to be changed to mediawiki Component 'History/Diffs'
mayby this is the same bug as bug 19716
