[PATCH v5 3/7] i18n: Rewrite gettext messages start with dash

[Jiang Xin <worldhello.net@gmail.com>]

Gettext message in a shell script should not start with '-', one
workaround is adding '--' between gettext and the message, like:

    gettext -- "--exec option ..."

But due to a bug in the xgettext extraction, xgettext can not
extract the actual message for this case. Rewriting the message
is a simpler and better solution.
