Looking at the output, I can tell that the file does exist in the
repository already.

I'm using the following python script:

"""
Python script to get revisions for a directory, for passing to svn admin
dump/load.
Usage:
svn log [url to directory] | python getrevs.py

Output, list of revision ranges on standard out:
rXXXX:rXXXX

Could be sent to dump/admin with the following shell script:

#!/bin/sh

while read rev; do
     svnadmin dump -r $rev --incremental PATH_TO_OLD_REPOS | svnadmin
load PATH_TO_NEW_REPOS
"""

import sys
import re

# Bad files I don't want to transfer over - all revs here are self
# contained.

exclude_revs = [5396, 5365, 5364, 5231, 5230, 5226]
revs = []
rev_re = re.compile(r'r(\d+)')
for line in sys.stdin:
     if line is None:
         break
     m = rev_re.match(line)
     if m is not None:
         # Found rev
         rev = int(m.group(1))
         revs.append(rev)

p_rev = -1
n_rev = -1
revs.reverse()
for rev in revs:
     if rev in exclude_revs:
         continue
     if p_rev == -1:
         p_rev = rev
         n_rev = rev
     else:
         if n_rev != rev - 1:
             print '%d:%d' % (p_rev, n_rev)
             p_rev = n_rev = rev
         else:
             n_rev = rev
print '%d:%d' % (p_rev, n_rev)

and then sending it to the following shell script:

while read rev; do
     svnadmin dump -r $rev --incremental PATH_TO_OLD_REPOS | svnadmin
load PATH_TO_NEW_REPOS
