x/tools/gopls: prioritise explicit upper case matches in completion results

[alecthomas]

In the general case I can see why case-insensitive completion makes sense, but if I've explicitly provided an upper case letter I would expect it to prioritise exact matches.

What's even stranger is that without entering any text at all, Name is the first option:

Thanks for the report. I think you're right: we should update our fuzzy matcher to prefer exact case match.

This is a gopls issue, so transferring to the gopls issue tracker.

There is a bonus for case sensitive match already here. I think the problem is we use the same bonus for matching the first letter of a segment, so the match bonus doesn't differentiate the case in this issue. It might work to just split those apart into separate bonuses.
