There's also the issue that the shell will perform wildcard expansion.

This probably doesn't directly matter unless you have files named
"region=<something>" in the current directory.

But users might spend time worrying about how to quote/escape it
without realising that it won't matter.

It might matter for the GUI, if its command-line handling doesn't
exactly mirror the shell's rules.

It might matter for shell scripts if the option's value is ever
separated from the region=part.

It would matter if we ever wanted to support the more conventional
"--option value" getopt syntax.

If the current region is selected with ".", maybe ".." for the default
region? Or even "DEFAULT" (that would preclude using a named region
with that name; but is that likely?).
