Each element has the form (STR POS COLUMN LINE FILENAME [TYPE]),
where STR is an error string, POS is the position of the error in
STR, COLUMN and LINE are the reported column and line numbers (or
nil) for that error, FILENAME is the reported filename, and TYPE
is 0 for an information message, 1 for a warning, and 2 for an
error.

LINE can also be of the form (LINE . END-LINE) meaning a range of
lines.  COLUMN can also be of the form (COLUMN . END-COLUMN)
meaning a range of columns starting on LINE and ending on
END-LINE, if that matched.  TYPE can be left out, in which case
any message type is accepted.")
