Lubomir Rintel 8af1404e54 generate-docs-nm-settings-docs-gir: remove space from the beginning of a para
From nm-settings-dbus(5):

Before (ugly, offensive, possibly in violation of geneva protocol):

  ...
  | set, the authentication retries for 3
  | times before failing the connection.
  |
  |  Currently, this only applies to 802-1x
  | authentication.

  ...
  | set, the authentication retries for 3
  | times before failing the connection.
  |
  | Currently, this only applies to 802-1x
  | authentication.
