When the users configure a DNS server on the interface, they likely
want to use it, regardless whether there is a default route on the
device.
For that to work, add an explicit "~" search domain.
Otherwise, by default NetworkManager only adds the special search domain
only on devices that have a "best default route" (nm_ip_config_best_default_route_is).
But that only considers a best default route in the main table, and
WireGuard (with ipx-auto-default-route) adds the default route to a
separate table. The heuristic to determine best devices works not well
with policy routing, so explicitly add this search domain during import.

We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
