Add option to jump if already open and/or open in new tab

[techhazard]

This commit adds a new setting:

g:fuzzy_opencmd opens the file with the specified command instead of the current one

Not setting g:fuzzy_opencmd is equivalent to setting it to 'edit' Examples:

'edit'      " always opens in current window
'tabedit'   " always opens in new tab
'split'     " always opens in horizontal split
'vsplit'    " always opens in vertical split
'drop'      " open in current window if unopened or jump to if it is open
'tab drop'  " open in new tab if unopened or jump to if it is open (note the space!)

Open in (v)split or jump is an exercise for the reader ;-)

Hey, thanks for this. I think I would prefer if there was just a g:fuzzy_opencmd variable that defaulted to edit, and the user could configure it to whatever they wanted to, ex tab drop in your case. If you make those changes I'll merge it in.

What do you think? Do you want me to remove the toggles as well?

[cloudhead]

Yeah I think the toggles are unnecessary.

[techhazard]

The way I see it: the toggles are an easy way to get started using tabs/jumps beyond that we have the opencmd that offers full customisability (which overrides the toggles anyway)

Would you mind leaving the toggles in place?

The problem is we're then using three global options to do what a single option can do. I think it's more confusing. Best would be to document usage of fuzzy_opencmd with examples of how to use it to open files in new tabs, or to drop into already open buffers. There's other ways to open files too, ex: split and vsplit, and there's no reason there should be an option to specifically open in a new tab, but not to open in a split. But we don't want to multiply the number of options!

[techhazard]

good point

I edited the first comment to reflect my changes

Great, thanks! I'll add your examples to the doc once I create it :sweat_smile:
