Shellcheck... about orc

[UlrichBerntien]

To pass shellcheck is a fine step. Now the shellcheck pass state could be hold at each change.

I also see ignore directives as a normal part of using automatic checks. The check programs will never cover all situations. The checks gives hints and a comment like "I read the hint, understand the hint, and decided it is ok to ignore the hin" is realy not cheating.

A second step could be to integrate some test, simple shell script file calling some functions of Orc or more sophisticated with kward/shunit2 or bats-core/bats-core
in the Travis CI build step.

But next I will focus me on the getnet rework.
