[PATCH 2/2] [INPUT] exit 127 if command_file is given but is a directory

[Gerrit Pape <pape@xxxxxxxxxxx>]

This commit makes dash exit with return code 127 instead of 0 if
started as non-interactive shell with a command_file specified as
argument that is actually a directory.

The wrong exit code was reported by Jari Aalto
