alpine's getopt returns "progname: unrecognized option: A"

I never thought that I'd have to fix a string concatenation problem in
a BusyBox awk program to generate VT100 code in a container, but here we
are:

echo | awk 'END {print "foo" "" ++a, "foo" ++a}'

should output "foo0 foo1", and for all the ?awk I tested, it does,
except for BusyBox awk who thought funny to output "0 foo1", breaking the
teken_state.h file.

... when the constructor has optional arguments

Fixes #2661.

See: https://github.com/Homebrew/homebrew-core/issues/26358

Add a new -v flag, just because we can.

* remember push errors in the context
* also fail additional pushes once we saw an error

Try to fail requests as early as possible. Otherwise just calling VDP
functions after an error is a noop.

Fixes #2618
