pub fn load_errors(testfile: &Path, revision: Option<&str>) -> Vec<Error>Expand description
Looks for either “//| KIND MESSAGE” or “//^^… KIND MESSAGE”
The former is a “follow” that inherits its target from the preceding line;
the latter is an “adjusts” that goes that many lines up.
Goal is to enable tests both like: //^^^ ERROR go up three
and also //^ ERROR message one for the preceding line, and
//~| ERROR message two for that same line.
If revision is not None, then we look
for //[X]~ instead, where X is the current revision.
