Are we talking about the same docstring?  I (having written it :-) find it
quite clear:

  "*Compilation motion commands skip visited messages if this is t.
Visited messages are ones for which the file, line and column have been jumped
to from the current content in the current compilation buffer, even if it was
from a different message."

"current" here refers to the same compilation.  When I compile again,
everything starts over.

How contiguous do they have to be?  How many lines apart may they be?  Keep
this in mind:  Where the old compile was bound to line-beginnings, the new one
can match a location anywhere on a line, even several different kinds on the
same line as in

foo.c:5: error: function f was declared differently at bar.h:17
foo.c:5: error: (this is some bla bla about the same spot)

To the human reader, the two foo.c:5 are still contiguous.   But to the
program bar.h:17 came in between.  It could get quite complicated.

What would we gain?  Why would I want to go to the same spot again if it is
mentioned 3 lines down, but not when it is mentioned on the next line?
