Description

Hi, very weird bug here. Saving the output with nufmt ./a.nu | save -f a.nu results in an empty file, but nufmt ./a.nu | lines | str join "\n" | save -f ./a.nu works fine for some reason.

Research direction

Start by reproducing the exact nufmt ./a.nu | save -f a.nu pipeline and compare it with the working lines | str join "\n" variant. Trace how nufmt output is passed to Nushell's save command and determine why the direct pipeline creates an empty file. Done means saving formatted output directly produces the expected non-empty file.
