new string in eog

[Felix Riemann <friemann svn gnome org>]

Hi,

just wanted to let you now of a string I just added to eog while
completing bug 559500:

"Error: %s\nRun '%s --help' to see a full list of available command line
options.\n"

This is shown on the command line when the user enters an unsupported
parameter. The first '%s' here is the error message that GOption gives
us while the second one is eog's command name. A translator comment is
in place.

Regards,

Felix
