[tor-commits] [tor/master] Disable default fallback directories when other directories are set

[nickm@xxxxxxxxxxxxxx]

commit 027f73f70ef49859d5c6b7dc2a231b3f78dafd10
Author: teor <teor2345@xxxxxxxxx>
Date:   Thu Apr 9 16:37:33 2015 +1000

    Disable default fallback directories when other directories are set
    
    Only add the default fallback directories when the DirAuthorities,
    AlternateDirAuthority, and FallbackDir directory config options
    are set to their defaults.
    
    The default fallback directory list is currently empty, this fix will
    only change tor's behaviour when it has default fallback directories.
    
    Fixes bug 15642; bugfix on 90f6071d8dc0 in 0.2.4.7-alpha. Patch by "teor".
