Temp files remain afterbecome

Could you clarify which temporary files you mean? I wonder if it's a bug of fzf.

The /tmp/fzf-{temp,proxy)-* files. I also thought that it might be bug of fzf, but after looking briefly at the code, I saw the comment below and figured that it's probably not, so I didn't look more into it:

fzf/src/terminal.go

Lines 4919 to 4922 in e4489dc

	case actBecome:
	valid, list := t.buildPlusList(a.a, false)
	if valid {
	// We do not remove temp files in this case

I just tested it. The temp files are now removed. 👍
