Add quotes to multiword arguments.

This adds quotes around multiword arguments before they are passed to
`/bin/sh -c` in an exec command.

Example:

I connect to irc like this:

    exec termite -e "mosh server tmux a"

Without this patch the arguments are passed to sh as:

    termite -e mosh server tmux a

When it should be:

    termite -e "mosh server tmux a"

For the command to work.
