Add back the "short" show output

[piotrb]

Current Terraform Version

Terraform v0.12.16

Use-cases

With the previous "short" output from show I was able to at a glance see what resources are being updated and how. This was extremely helpful. This way its easy to spot changes in resources that are unexpected by the recent changes to the TF files.

Attempted Solutions

N/A this was a removed feature.

Proposal

If you guys are that keen on keeping the "long" output, I'd like to see a new command line flag .. eg --short or something that would allow seeing the old output.

Original change that removed this behavior - #23292

One possible workaround (for now):

terraform show -no-color | grep -E '^\s*# '

Even though I enjoyed the previous output format, the - and ~ were sometimes not clear enough on smaller fonts.

I agree with this! We leveraged the shorter version to roll up a summary report on a PR.
