Bug#861059: a shell script needn't end in .sh

[積丹尼 Dan Jacobson]

Package: bash-completion
Version: 1:2.1-4.3
Severity: minor
File: /usr/share/bash-completion/completions/sh

$ sh -x bin/<TAB>
backup_attempt.sh       heavens-above-which.sh

actually any file should be a candidate, not just ".sh" files.
