-* Error lines
-  <Space> <New> <SrcLineNo> <Error>

-  - <New> is either 'n' for new errors, or 'o' for old ones.
-  - <SrcLineNo> is the 1-base line number of the error in the source log file.
-      If there is no source line then this should be 0.
-  - <Error> is the error message.

 Returns the errors in the same format as TagNewErrors().
