0) Problem
Checksum files for incremental XML data dumps are not formatted correctly. This causes `md5sum' to throw an error.
1) Test case
(shell) wget -nH -np -nv -N -r -l 2 http://dumps.wikimedia.org/other/incr/simplewiki
(shell) cd other/incr/simplewiki/
(shell) ls
simplewiki-20140703-md5sums.txt
simplewiki-20140703-pages-meta-hist-incr.xml.bz2
simplewiki-20140703-stubs-meta-hist-incr.xml.gz
(shell)$ cat simplewiki-20140703-md5sums.txt
d03f3a91ef0273eb814f39a1d13788cb
c51f2bd5ef6bd42ce65cf4a7fca72400
(shell)$ md5sum --check simplewiki-20140703-md5sums.txt
md5sum: simplewiki-20140703-md5sums.txt: no properly formatted MD5 checksum
lines found
(shell)$ cat simplewiki-20140703-md5sums.txt
d03f3a91ef0273eb814f39a1d13788cb

2) Recommendation
The correct format is:
<checksum><two spaces><filename><newline>
Sincerely Yours,
Kent
