Flashing the matching lines is very distracting.  And even though
there is a variable `compilation-highlight-regexp' to disable the
highlighting, when it is disabled, there is no indication at all.

So I think a better indication method is needed.  For example,
the same methods of the compilation buffer could be used: aligning
the source file window on specified context lines (though this is
not good for source buffers), or setting the fringe arrow.

Another good indication method is persistent (i.e. non-flashing!)
overlays highlighted with a special face on matching lines in
compilation output buffer and source code buffer.
