### Please describe the problem.
I've a type=directory remote, with exporttree=yes on a USB disk. when running `git annex --content` git annex list a long list of `export cibox-usb toto ok` lines for file it already exported before. I’ve check some of those file, and their content are correct.

Those line hide real new export, and I wonder if it doesn’t slow the process.

There seem to be no way to tell git-annex that those file are already ok, and it should try again to export them.
`

### What steps will reproduce the problem?

Just running `git annex --content name-of-the-remote`

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
It’s only a bug on what git-annex display. It does the asked work: the file are correctly exported where I look for them.
