Worked on bash tab completion some more. Got "git annex" to also tab complete. However, for that to work perfectly when using bash-completion to demand-load completion scripts, a small improvement is needed in git's own completion script, to have it load git-annex's completion script. I sent a patch for that to the git developers, and hopefully it'll get accepted soon.
Then fixed a relatively long-standing bug that prevented uploads to chunked remotes from resuming after the last successfully uploaded chunk.
