Fix diff skipping lines (#13154)
* Fix diff skipping lines ParsePatch previously just skipped all lines that start with "+++ " or "--- " and makes no attempt to see these lines in context. This PR rewrites ParsePatch to pay attention to context and position within a patch, ensuring that --- and +++ are only skipped if appropriate. This PR also fixes several issues with incomplete files. Fix https://codeberg.org/Codeberg/Community/issues/308 Fix #13153 Signed-off-by: Andrew Thornton <art27@cantab.net> * Add testcase Signed-off-by: Andrew Thornton <art27@cantab.net> * fix comment * simplify error handling Signed-off-by: Andrew Thornton <art27@cantab.net> * never return io.EOF Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: Lauris BH <lauris@nix.lv>
