This just matches the passed pattern against the full source path with
filepath.Match which, in contrast go filepath.Glob, doesn't match the
directory separator with '*' and is not terribly useful that way.
Someone should replace that by a more sophisticated matcher.
When restoring an item fails with ENOENT, create parent directories and
try again. This is needed for restoring partial trees (as in: the Filter
function didn't return true for the paths leading up to this restore
item).
The source path is probably more useful here as the user, when
restoring, probably wants to filter for /usr/local/foo instead of
/tmp/restore-whatever/{usr/local/,}foo.
