Port read tests to expect Note: This includes a super cheesy thing to print variable contents. The expect version has one that's a bit more elaborate (featuring a marker setup), but tbh that doesn't seem to be worth it. If we do need it, we can add it, but it seems more likely we'd just do `set -S`, or do it in a check instead.

def expect_read_prompt():
Work around wants_terminal not begin set inside eval On this binding we fail to disable CSI u bind c-t ' begin set -lx FZF_DEFAULT_OPTS --height 40% --bind=ctrl-z:ignore eval fzf | while read -l r; echo read $r; end end ' because for "fzf", ParseExecutionContext::setup_group() returns early with the parent process group (which should be fish's own) , hence "wants_terminal" is false. This seems questionable, I don't think the eval should make a difference here. For now, don't touch it; use the more accurate way of detecting whether a process may read keyboard input. In many of such cases "wants_terminal" is false, like echo (echo 1\n2\n3 | fzf) Fixes #10504
