Good points all around, and I don't have much more to contribute :)

We do this currently already, and the idea is that all external errors are 
converted into local errors on line 1.
In the error list they appear with a file name and a line number in that file, 
so if you were to cycle errors relative to that list you would visit files one 
by one, and if you were to visit errors relative to the buffer you'd go through 
all local errors then jump to another file with errors, if any.
