Boar fails silently on md5 collision

What steps will reproduce the problem?
1. Add two distinct files with the same md5 checksum to a working dir (ex.:
"hello.exe" and "erase.exe" from
http://www.mscs.dal.ca/~selinger/md5collision/);
2. Check in - one blob overwrites the other;
3. Check out to a new working dir - now there are two files, but with the same
contents (instead of two different contents).
What version of boar are you using? (Mercurial change id or daily build
date)
boar-29-Jul-2012-setup-win32.exe
Note: I know md5 collisions - in "regular" files - are rare (especially if both
files have the same length like in the example above) but it's still a
possibility to have your backups corrupted without noticing, so IMHO it should
be accounted for.

Sorry, when looking at the existing issues somehow I missed Issue 16... you can
close this as a duplicate.
