ARM/ASM: Inconsistent exit codes upon errors

[ahmetb]

Haven't dug so deeply however I can tell certain errors do not exit with a non-zero exit code upon failure:

$ azure vm foo; echo ExitCode=$?
error:   'foo' is not an azure command. See 'azure help'.
ExitCode=0

vs

$ azure account set; echo ExitCode=$?

  error: missing required argument `subscriptionNameOrId'

ExitCode=1

This is not ideal. Imagine someone having a script like:

doThis && \
    doThat && \
    azure account seth <subs_id> && \
    dropNuclearBomb

the error will not be effective and script will keep going instead of exiting.

Also an example from git:

$ git foo; echo ExitCode=$?
git: 'foo' is not a git command. See 'git --help'.

Did you mean this?
    log
ExitCode=1
