Review prompt is very verbose

[qoh]

It takes a some scanning to actually parse the prompt of available options as you're reviewing a package for merge or build, due to how long and wordy it can get:

[D]=view upstream changes since your last review, [M]=accept/merge upstream changes, [S]=(shellcheck not available until you merge), [T]=run shell to edit/inspect, [O]=(cannot use the package until you merge)

Some comments, all opinionated - I would prefer these changes, but it could also be behind an option:

• since your last review probably isn't necessary, it could just be view upstream changes;
• pick one of the words in accept/merge upstream changes like accept, and shorten to accept changes;
• inapplicable actions shouldn't be shown: [S]=(shellcheck not available until you merge);
• run shell to edit/inspect could be review in shell;
• inapplicable actions shouldn't be shown: [O]=(cannot use the package until you merge)--this one specifically makes some sense to list since it could otherwise be confusing (but it still is for some), but that could be resolved in other ways, such as: moving the merge action first/last and appending and continue.

All in all that prompt could, for example, be:

[D]=view upstream changes [T]=review in shell [M]=accept changes

---

For the next step:

[S]=run shellcheck on PKGBUILD, [D]=(identical to upstream, empty diff), [T]=run shell to edit/inspect, [O]=ok, use package.

• (identical to upstream, empty diff) is a bit of an odd action to list, surely this could be omitted, or worded better and more succintly;
• ok, use package. could just be continue.

That could be as simple as:

[S]=run shellcheck on PKGBUILD [T]=review in shell [O]=continue

---

It might also be worth it to have a ? action that explains the current state further, what rua is expecting the user to do, and what each action is for.

As an extension to the above proposal, I would also like to propose to add default action at each step, similar to say apt-get install's accept change [Y/n], Y is the default action (if you do not type anything and press enter that option is chosen).

For eg., accept changes as the default action for the first step and ok as the default for the next step like

[d]=view upstream changes [t]=review in shell [M]=accept changes

[s]=run shellcheck on PKGBUILD [t]=review in shell [O]=continue
