This makes it possible to expand the signals checked by the type. I can't merge
the sigttin fixes for #7060 yet because they introduce new breakage, but this
will make merging any future fix easier.
This was intended to stop showing the user "unimportant" variables,
but it just didn't complete them entirely, even if the current token
starts with a dunder (or `fish` of all things!).
Because completions sort `_` last, let's just complete these always
and let the user filter them.
This wasn't added to the prompt status order, so it was computed and
then not used for the informative prompt.
We still check later if we should compute it, so this is harmless if
showstashstate is unset.
Fixes#7136.
In #7133, neovim crashing caused "OPOST" to be turned off, which
caused a weird staircase display.
So we just force a set of settings that don't seem useful to change to
avoid breaking the terminal with something like that.
Fixes#7133.
A broken/missing optspec or `--` is a bug in the script using
argparse, an unknown option or invalid argument is a bug in using that script.
So in the former case print a stacktrace, because the person writing
the `argparse` call is at fault, in the latter don't.
Fixes#6703.
The `snap interfaces` command prints out a deprecation notice to stderr. This breaks the completion
support for interfaces, connect and disconnect commands like so:
```
$ snap connect <TAB>error: no interfaces found
error: no interfaces found
...
'snap interfaces' is deprecated; use 'snap connections'.
'snap interfaces' is deprecated; use 'snap connections'.
'snap interfaces' is deprecated; use 'snap connections'.
error: no interfaces found
error: no interfaces found
'snap interfaces' is deprecated; use 'snap connections'.
```
Ultimately, the snap command completion should switch to `snap connections`. However, for now try to
workaround the notice by redirecting stderr.

This was sometimes slightly annoying in porting.
5 is enough most of the time, 10 should be enough basically always,
without being too annoying if you don't need it.
Note: This includes a super cheesy thing to print variable contents.
The expect version has one that's a bit more elaborate (featuring a
marker setup), but tbh that doesn't seem to be worth it.
If we do need it, we can add it, but it seems more likely we'd just do
`set -S`, or do it in a check instead.
