We're migrating our repos from in-house servers to bitbucket. So need to 
convert our largefile-enabled repo to an non-largefile repo. This 
function needs hg convert to un-largefile the repo. Secondly, we've 
realized that subrepos was a mistake, but I cannot and must not undo the 
linking to the subrepos. So we must retain the subrepo information 
stored, but it can well and good be just in text files not automatically 
recognized by hg.

Yes, I'm prepared that this will be necessary, but I'm stuck at what hg 
convert is failing on. E.g. what asset I need to modify to get hg 
convert pass.
