In #2202 the root issue was that the user was running in an unreadable working directory, and so gomplate errored with a message like:
Rather than ignore errors when the default config file can't be read (which will hide real failures and perform the wrong behaviour potentially), this PR adds the ability to set
--config
or$GOMPLATE_CONFIG
to an empty string, which will cause the config file parsing code to be skipped entirely.
