At first - yes, but later i noticed other error patterns and tried them iteratively; maybe some edit distance metrics can find more.

Ideally FileCheck should prefix commands with some tag to distinguish comments from filecheck annotations, like
`--command-tag=@` and use as `@CHECK: xxx`, `@MYCHECK-NEXT: yyy`, etc. Making typo\error in both prefix and command tag will be harder, i guess.
