Expected result

Restic appears to try and remove extra layers of hierarchy from pathnames, but sometimes this fails.
For example I tried running restic backup /home/wscott /space/wscott but the resulting snapshot only contained 'wscott' that matched /home.

In the above example 'file5' is missing from the restore. It is inconsistent. Sometimes file4 is missing.

Indeed, it is a duplicate of #549, I'll close this one and improve the title of the #549.
