Add option to hide listBinds when pressing keys

[dazzywi]

Hello, I wanted to make an option that hides the bindings popup that shows up every time you press some sequence of keys.

Why? Because it can obstruct some files at the bottom of the screen. And moreover the pressed keys are already shown by default if "rulerfmt" has %a expansion (as seen on the screenshots below, on bottom right of my window, when I press g)

Here is example, when the new drawbinds option is set to true (that is, by default)

And here is after, when the drawbinds option is set to false, and pressed any key

I was thinking about the name of the option as well. Mainly because there are already some toggleable options that are named in different convention, like hidden or preview, and no option (that I know of at least?) that has "show-" in the beggining of its name, but I think it sounds reasonable too.

Since the function in ui.go called listBinds I think it's more appropriate to go with "-binds," but might also consider showkeys or plain listbinds in all lowercase?

Do I need to submit another commit with changes here or open a new one?

I would say that the convention is to keep the option name as concise as possible, without being too ambiguous in its meaning. In the context of file managers, the meaning of hidden and preview should be self-explanatory, but the meaning of binds by itself is not clear.

So showbinds was the first thing that came to my mind, but I suppose listbinds is also okay too.

For the PR itself you can just keep adding new commits, no need to force-push. All the commits will be squashed into a single commit anyway when merging to the master branch.

I chose to go with showbinds, since it also was my idea from before I looked in the CONTRIBUTING note. Also changed placement of this option in documentation files since they all appear to be sorted alphabetically.

(And i'm not sure why but my editor keeps changing other lines in the file, like urls you see in diff files? Maybe something to do with indentation, sorry if this is inconvenient)

You must have your text editor configured to somehow delete \n characters at the end of the file, the CI check is currently failing.

The rest of the changes look fine, so if you can fix the line endings then I will approve the PR.

[dazzywi]

Should be done now I think, just did go fmt within my fork

[joelim-work]

Just out of interest, how did you add the \n characters back? I think if you do the same for doc.md, doc.txt and lf.1 then the diffs should disappear.

Actually it's probably fine I can fix it myself. Will merge it now then.

Thanks once again.
