This looks great.  Let me just check my understanding here.

The doc string talks about "the next error in the current buffer".  This
means the next error following the error that was last found my the
next-error-function, not the next error after point.  So to support the
next-error-function I need to maintain an additional bit of state saying
which error in my buffer, if any, is the current error for the purposes
of next error function; if my next-error-function is called with a
non-nil RESET, I change the current error to be the first error in the
buffer.  

If the user wanted to use next-error to run through the errors from an
XSLT processor, say, instead from nxml-mode, then they would make the
compilation buffer be the only one displayed in the frame before calling
next-error.

Have I misunderstood anything?
