exclude .ssh directory about gitlist

[kulbirsaini]

Actually, we should consider excluding all the dot files or directories in the root of path specified using repositories option in config.ini. Example,

/home/user/
          ├── .gconf
          ├── .dbus
          ├── .gem
          ├── .dropbox-dist
          ├── my-public-project
          ├── linux

All the directories starting with dot are of no use to gitlist.
