I have attached a htmlfontified compilation buffer showing this. It also shows that the parser of the compilation buffer gets confused by this. The problematic line is: " ./config.go:10:5: other declaration of config_file" Some code thinks the whole line is a file name, because the whole line is a hyperlink (underlined). Some other code thinks only the beginning of the line is a file name (red). But this part also thinks the line number is part of the file name and marks the column number as line number (purple). I think it might be ok to ignore leading whitespace, because file names do not start very often with whitespace. --0000000000002c1be405f33cedfe Content-Type: text/html; charset="US-ASCII";

If a major mode starts compilation, presumably it knows the error message format and could set up that one compilation buffer accordingly without having to add to global error message parsing.
