If someone needs a full-blown diff, here it is.  I just tested it
and the toggle in "Station->Filter Display->Display Aloha Circle"
comes up as default off now when Xastir is started.  Note that it
takes a half-hour after bringing up Xastir with a local TNC before
the Aloha circle is computed and displayed.

For those that don't know what a "diff" is, it's a difference file
between two versions.  You apply this particular patch like so:

Save the text between the lines in a file, let's call it
"aloha.patch" in this case.

    cd xastir/src
    patch -p0 <aloha.patch

Of course editing one line in main.c is probably easier than
applying the patch using "patch" in this case.  It's easy to see
that the line containing '1' is replaced by the line containing '0'.
