Change defaults to be consistent with original defaults and REPL perf…

[cottrell]

Happy to hear feedback on why whatever is currently going on is better but seems like generally it is best to not dramatically change the defaults. . is one of the most important operations in python (IPython) from a human perspective so everyone is quite sensitive about this stuff.

Case-insensitivity break tab-completion in the case when there is one case-sensitive choice but several case-insensitive choices. Would be interesting to consider second to be case insensitive or something like that. Then you don't break that UX on the first tab completion.

I'm happy with the bit setting jedi to do case-sensitive completion, but I'd rather leave the default presentation as 'multicolumn'.

K, I've just done the case-sensitive one-line change.

Thanks, merging. We may want to refine this further (e.g. falling back to case-insensitive search when we find no matches), but it sounds like this will be an improvement for most users.

That's always a dangerous thing to say. If there are people who don't like this change, they won't be complaining yet. 🤞 Fingers crossed...

Ah, yes falling back in the case of no-matches ... I will try to remember to have a look if it is quick to do. This functionality could actually save me time when teaching people new things.
