fix: multiline input should have newline

• [x] I have reviewed CONTRIBUTING.md.
• [x] My commits and title use the Conventional Commit format.

• [x] I have documented changes and additions in the CHANGELOG.md.

When multiline is needed, a newline should be added to the input, much like what other shell would do.

Before newline addition:

& echo "abc
> def"
abcdef

After newline addition:

& echo "abc
> def"
abc
def

However, there's runLuaRunner(...) call in exec.go:126 I didn't test for, might be breaking.

i intentionally removed this very early in hilbish's life (3 years ago) due to me commonly missing quotes for my commit messages (and a newline being annoying most of time, in cases like that).

if anything, you can make an addition that input ending with something like \ will include a newline if you like.

i see, understandable

though, knowing Hilbish is not aiming to be POSIX-Compliant, maybe Hilbish should consider making a documentation for what these different behaviors would be, it's nice for quickly knowing what differs, and what to expect in Hilbish

either way, thanks, i will close this
