[git commit] lineedit: fix printing lines during tab completion

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=37abfb919dfa92132bc7a14c583016a46026729b
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

Indentation and escape characters are all output to stderr now, but the
matches themself remained on stdout leading to garbled output on Tab
completion.

Print the results to stderr as well to fix this.
