Whitespace improvements.
Remove unnecessary loops, perform some code consolidation, and add some
additional error checking/reporting.
Improve the INDEX format. Whitespace improvements, format improvements, typo
and grammatical fixes.
Oops, in SVN r251905 I forgot that f_die takes the return code as the first
argument (not the format).
Switch bsdconfig `Disk Management' from sade(8) to `bsdinstall partedit'.

Change the f_dialog_msgbox() arguments in `dialog.subr' to accomodate an
$hline argument for setting the --hline parameter value. This change does
not effect any current modules as it turns out that not one single usage of
f_dialog_msgbox() relied on accepting more than a first argument (read: all
occurrences quoted the first parameter; so $* was never depended upon).

This will allow some custom invocations of --msgbox to roll over to this
function (for example, in `mouse/disable').
Use newly enhanced f_dialog_msgbox() from SVN r251912.

Remove unnecessary loops, perform some code consolidation, and add some
additional error checking/reporting. (same thing going on here as SVN
r251905 -- just this time for the mouse module instead of console)
Perform some code consolidation and add some additional error
checking/reporting. (similar to SVN revisions 251905 and 251915)
