5.2: Fix pollution with global variables

[jansorg]

Fixes some of the pollution with global variables.

We're dropping the default of s/step for the "last command", because it's breaking tests and is potentially confusing to users. Previously, the default was not applied because the other places used a _Dbg_ prefix (i.e. the name here was wrong and the default was not used).

I really like this!

However, when I try it things are failing for me. Let me see if I can get CircleCI working for this first.

I think that tests were passing locally...
Any objections if I tried to add GitHub Actions CI in addition to your Circle CI setup?

This would be awesome. Please do it!

All good -

I just checked the behavior of gdb 14.0.50 and it does not default to s/step initially either. However after a step is done, that hitting enter will continue stepping. And that is how bashdb works even after this change.

Testing now works for me. Many thanks!
