Hi,

I've made a change to my copy of ocamlc to modify error messages when 
they cover multiple lines.

For example, for the following code, the modified error message includes 
the line number and character offset of then end of the message instead 
of just the length of the message.

Would there be any interest in me making the change everywhere and 
submitting it as a patch?  I see about a dozen places in the source of 
the various tools where the change would be possible.   One concern I 
have is that it might break automated test scripts.
