Ah, I just took a look at Tools/scripts/make_index, and found the
following:

# Save where we are so that we can map all directories formed
# from ${PORTSDIR} to their canonical location '/usr/ports/...'.
chomp($pwd = `pwd`);

# Read each line of output generated by the 'index' target.
while (<>) {
    chomp;
    s/\015$//;

    my @f = split(/\|/);

  # Force to canonical form.
    $f[1] =~ s!^$pwd!/usr/ports!o;
    $f[4] =~ s!^$pwd!/usr/ports!o;

So, I take it, the index file is *supposed* to always map port paths to
"/usr/ports", regardless of where the ports tree is actually located?

Seems a little odd to me, but if that's the case, I guess I'll have to
make some adjustments to mkreadmes.
