Added check for return code when checking for bzr.
Review Request #11196 — Created Sept. 21, 2020 and submitted — Latest diff uploaded
When pyenv is in use and the needed executable is only available in a
different Python version, pyenv intercepts the call and will print
an error/return 127.When running bzr help under these conditions, we see this:
pyenv: bzr: command not foundThe `bzr' command exists in these Python versions:
2.7.14
Tested 'rbt post' manually in my local integrations repo with the changes.
