No. These settings should be ignored on Windows and OS X; they should only be
used on the rest of the UN*Xes.
It must also be possible for Wireshark to behave correctly if those environment
variables aren't set. It must, for example, be possible to plug an old VT100
into a serial port on your machine, fire up getty on that serial port, log in,
and run TShark and have it find your settings. It must also be able to find
your settings if you switch from a desktop environment that doesn't support the
settings to one that does or if you switch from one that does to one that
doesn't, at least in the default configuration for the desktop environment.

The spec does not contain the word "temporary", so we should continue to store
them in $TMPDIR.

Absolutely. If a version of Wireshark that supports these settings can't find
settings created by an earlier version of Wireshark that doesn't support them,
that would be completely unacceptable and we would not implement it.
