- Support passing an arbitrary path to the shellcheck configuration file
with the BASH_CONFIG_FILE_NAME variable. This brings shellcheck in
line with other linters that support configuration files.
- Enable shellcheck external sources using a directive in the
configuration file, so users can eventually override it if not needed.
- Export command configuration variables that subprocesses might need.
Close#5414
* Improve wording of LINTER_RULES_PATH docs (#1634).
* Add a template config file for ShellCheck (#1633).
Instruct ShellCheck to search SCRIPTDIR, the directory that the script
being linted is in, for other scripts that are sourced. Otherwise, the
commonly-used source command results in linter error SC1091. See
https://github.com/koalaman/shellcheck/wiki/SC1091 for more details.
* fix line ending
