But, bash completion is also crap with : , so ..

You can use the fsck subcommand to check for problems in your data. What
can be checked depends on the key-value [[backend|backends]] you've used
for the data. For example, when you use the SHA1 backend, fsck will verify
that the checksums of your files are good. Fsck also checks that the
[[numcopies|copies]] setting is satisfied for all files.
# git annex fsck
fsck some_file (checksum...) ok
fsck my_cool_big_file (checksum...) ok
...
You can also specify the files to check. This is particularly useful if
you're using sha1 and don't want to spend a long time checksumming everything.
# git annex fsck my_cool_big_file
fsck my_cool_big_file (checksum...) ok
If you have a large repo, you may want to check it in smaller steps. You may
start and continue an aborted or time-limited check.
# git annex fsck -S <optional-directory> --time-limit=1m
fsck some_file (checksum...) ok
fsck my_cool_big_file (checksum...) ok
Time limit (1m) reached!
# git annex fsck -m <optional-directory>
fsck my_other_big_file (checksum...) ok
...
Use `-S` or `--incremental` to start the incremental check. Use `-m`
or `--more` to continue the started check and continue where it left
off. Note that saving the progress of `fsck` is performed after every
1000 files or 5 minutes or when `--time-limit` occours. There may be
files that will be checked again when `git-annex` exists abnormally
eg. Ctrl+C and the check is restarted.
