As I understand it, the algorithm needs to work like this:
1. For each patch hunk:
2. Filter out all lines that match /^-/
3. Remove the first character (" " or "+")
4. Normalise EOL characters: s/\r\n?/\n/
5. Over the entire hunk, find any case that matches
/({|\n)\s*\n\s*(\n|})/ where \s matches all space characters except
\n.
6. Report the middle line the preceding regular expression matches to the user.
I'm confident I can write it as a shell script, but I don't know
enough Perl to add that test to checkpatch.pl
Thanks,
