I just did this for a vendor branch from GDAL 1.4.4 to GDAL 1.5.0.

So it's clear, that there should be major changes, but the
snv_load_dirs.pl script offered me about 180 files that where deleted in
1.4.4 and about 320 files that where added in GDAL 1.5.0
The script presents this listing on the screen with a page functionality
to offer a renaming detection by the user.
However the sorting of the files was not reasonable:
- You had to scroll alot forward and backward to see, if anything was
perhaps just renamed.
- The files looked not sorted at all.
I would render this renaming useless for such a jump, it was helpful
before (1.4.2 to 1.4.4).

However there could be big help by a gui frontend like in TSVN for
sorting this deleted / added listing for different aspects.
I think it would be helpful if there where different methods to
calculate the 'distance' between files:
- filenames... maybe there was a change from Uppercase to Lowercase,
added some '_' character to make filenames more readable ....
- have a brute force method to calculate a kind of 'diff'-distance
between each deleted / added pair. Maybe a diff distance could be
something like the size of a patchfile.

With this there could be sorting that gives hints which files should be
treated as rename.
