Empty (excluded?) directories get lost in restore

[raimi]

Noticed on using shaback to clone and adjust some machines: Empty and/or excluded directories get lost.

Problem (on Debian):

• With missing /var/log/apache2/ apache won't start since it can't log.
• With missing /var/log/fsck/ some logsave(8) processes wait forever

The actual problem are probably our (pi) default exclusion rules - but i wouldn't know a rule to exclude every file from /var/log/ retaining the subdir-structure...

Update 2013-01: This is problem! I just had to recover my entire root-filesystem and the recovery was incomplete. Special directories /dev /sys and /tmp were to created by the recovery process! The directories were part of the repo but they happened to be empty (because they are mount points or were just empty).

How to reproduce (probably, I did not try):

mkdir -p /foo/bar
shaback backup /foo
shaback restore /foo

Bug: empty directory "bar" is not created inside foo.

Depends on how you exclude directories:
Exclude even the directory itself:
addExcludePattern('/foo')
Exclude what's inside the directory:
addExcludePattern('/foo/*')
