Subject: [PATCH] macOS: Fix regression in 0.26.0 that caused asking the user
 for a line of input such as for set_tab_title to not work

Apparently libedit doesn't work in the forked process when the parent
process is run via Launch Services. I cant be bothered to investigate
why, given that libedit is closed source. macOS users will just have to
live without history/completion in the ask kitten until I get around to
writing a replacement for readline/libedit.

And on a personal note, macOS >> Necrotizing fasciitis

Fixes #5447
