fullscreen: use eval to improve appearance of suspended job.

There is a difference between Bash 4 and Bash 5. When a command
which has been invoked by syntax like:

  command "$@"

is suspended by Ctrl-Z, Bash 4 shows, as the displayed job string,
the real program that is running, and its arguents. Whereas
Bash 5 just shows the above unexpanded 'command "$@"' syntax!

To work around this, we expand "$@" ourselves, and eval
an expanded command.

* basta.sh (basta.fullscreen): Expand the command arguments into
a properly escaped variable with the help of the %q argument of printf.
Then we eval the command. We keep the LINES=$realrows out of the
command, putting that into the eval, otherwise that will appear
in the jobs also. The cosmetics is improved. For instance if the
Bash 5 user has an alias like "alias vim='basta.fullscreen vim'",
and then runs "vim file" and suspends the editor into the background,
they will see "command vim file" as the job name, rather than
LINES=$realrows command "$@".
