Here's a tiny Perl script I wrote for this purpose once in a fit of
pique.  Use the -i option to specify the 'input' directory prefix
(i.e. in the --- line) and -o to specify the 'output' directory
prefix.

#!/usr/bin/perl -p
use strict;
use File::Basename;
use vars qw($in $out $path $name $dir);

BEGIN {
    my @args;
    while (defined($_ = shift)) {
	if (/-i/) {
	    $in = shift;
	    $in =~ s,$,/,;
	    $in =~ tr,/,,s;
	} elsif (/-o/) {
	    $out = shift;
	    $out =~ s,$,/,;
	    $out =~ tr,/,,s;
	} else {
	    push @args, $_;
	}
    }
    $out ||= $in;
    $in  ||= $out;
    @ARGV=@args;
}

/^Index: (.*)/ and do {
    ($name, $dir) = fileparse($1);
};
/^(---|\+\+\+) ([^\t]+)/ and do {
    die "Your CVS isn't broken, $2 doesn't match $name\n" unless $2 eq $name;
    my $prefix = ($1 eq '---') ? $in : $out;
    s,$2,${prefix}${dir}${name},;
};
