Relying on dialog auto-sizing (width/height/rows = 0) is a mistake
Use the provided API for calculating the appropriate size of menus

Remove unnecessary quotes

Add missing quotes

In awk, if you're going to append a newline to your printf
AND you're going to print only the argument, just use print

This statement has too many backslashes

Neither printf (and as is commonly known) nor print need parens in awk

Whitespace and alignment

You don't need parentheses for awk's printf

Continued resolution of conveluted statement
We shouldn't be coding things like "x || (x && x) || x || x || x ..."

These two error messages have always been backwards since inception

Why use $? when you can use the command itself

If the first ping succeeded, why on Earth should we ping it again?

Start deconstructing a conveluted hunk of code

Remove completely unnecesary parentheses

Why repeat yourself when you can send stderr to the same place as stdout?

Properly quote variable

Use more generic f_yesno() from provided API

The output of dialog needs to be sanitized
for portability/compatibility requirements

Whitespace alignment

Sort the domains

The --no-items and --stdout options are non-standard and should be avoided

From the dialog(1) manual:
using [--stdout] in portable scripts is not recommended

More efficiently make use of the exit status

Stop repeating strings (centralize prompt string)
NB: Changes to strings now only affect a single line

Add missing backslash (no real effect; it's pedantic and correct for
the interpolation level)

Use the oft-neglected awk syntax "startcondition, stopcondition { ... }" to
process the range of country labels which appear as columnar list from the
"ifconfig DEV list countries" command. Not only

Use the oft-neglected awk syntax "startcondition, stopcondition { ... }" to
process the range of country labels which appear as columnar list from the
"ifconfig DEV list countries" command. Not only improving maintainability,
but also properly encapsulating arguments in single-quotes instead of
trying to escape whitespace. It is also completely unnecessary to collapse
newlines into whitespace (shell will do this for you automatically upon
expansion of the contents where necessary).

NB: This also changes the sorting algorithm to sort on the country code,
not the country name. The type-ahead feature of dialog is destroyed if the
tags are not sorted properly.
