An output:match is performed to detect the header of the linter output to exclude it from being injected into the buffer.
However, it matches on ==, which is also a legitimate Ruby operator.
When == is encountered in the code, it causes the buffer up to and including that operator to be deleted.
Because the linter output uses 16 = symbols in its header, adding an additional == to the match will still work while not causing false matches with legitimate uses of ==.
