feature: set FZF_SELECTION env var containing text of selected item

[kuremu]

Sets FZF_SELECTION to the ansi-stripped text of the currently selected item in t.environ(), essentially inserting the value of {} into the environment. If there is nothing in the list, FZF_SELECTION is set to an empty string.

fzf --bind "focus:transform-prompt(echo \${FZF_SELECTION}\>\ )"

This would be useful to me as my reload/transform calls have become pretty complex, and I'm already capturing the other FZF env vars.

I'm not sure about this (at least not yet). You can already do this with current={}; rest_of_the_command. And by doing this, we're pushing the current item to every child process, whether they need it or not. And in some cases, it can be quite lengthy (e.g. minified JS files, single line of hundreds of KBs), so it might cause some problems.

I see what you mean, no worries I'll close this for now
