Are you really sure your messages span over more than one line. Looking at your data, it seems to me that they are each on one single line, but just displayed at the screen on two lines because they are two long to fit on one line. The reason I am thinking that is that it does not seem to make sense to put a new line sometimes after "into", sometimes after "into \DSM", sometimes after "into \DSM R11\project".

Actually, I tried to copy and paste your data into a text editor, and there is no newline character in the middle of the lines. Inserting them here between <code> tags shows a different newline pattern:

In brief, there does not seem to be new lines within your error messages. It seems to be merely a screen display artifact.
