zi automatically selects only initial result

[azaleacolburn]

Description

zi foo will now automatically select the only initial result if applicable, as per #997.

Usage

The command zoxide query --interactive foo will now automatically select the only result initially returned, if there is only one. If there is initially more than one result, but further fuzzy-finding narrows it down to just one, that final result will not be automatically selected.

Environment Variable

A new environment variable _ZO_ZI_ONLY_RESULT has been introduced which toggles the behavior described above with the current behavior of zi.

Hey @azaleacolburn, thanks for sending in these PRs. I really appreciate the help! One small request though - can you tag me before picking up something? I may have a different implementation in mind, so I could probably save you some time there.

For this particular issue, I think this would be the cleanest solution:

• Currently, zoxide uses certain default flags for fzf, which the user can override with _ZO_FZF_OPTS.
• We can add a flag called _ZO_FZF_OPTS_EXTRA that adds flags on top of the default ones, rather than replacing them.
• Once that works, users can get this behaviour with the following setup:

export _ZO_FZF_OPTS_EXTRA="--select-1"

@ajeetdsouza @azaleacolburn Just seing this PR and your answer, funny but I just opened a PR to support _ZO_FZF_EXTRA_OPTS.
#1026

I can rename the flag if you prefer.

@ajeetdsouza Thank you! I'll be sure to tag you going forward. I didn't realize the --select-1 option existed. I agree that it's clearly the cleanest solution. I'll close this PR and respond to #997 letting them know about #1026 and the select-1 flag.
