[issue23441] rlcompleter: tab on empty prefix => insert spaces

[Martin Sekera]

Martin Sekera added the comment:

In the end it doesn't matter what characters end up on the terminal. What matters is the UX of not having to press backspace several times to unindent. That's sloppy design.

The issue of forcing a custom indent width on a user who might have their tab stops setup differently is another, albeit smaller, issue. I think the interpreter has absolutely no reason to do what's basically UI work (aligning tabbed text with tab-stop columns as in the first patch). That's the terminal's job.
