Subject: [PATCH] Bash: add support for hyphenated param names

Previously, a parameter (flag) such as `curl --upload-file` would not be
properly recognized, because of the hyphen in the parameter name. This
commit causes `--upload-file` to be properly recognized as a parameter.

fixes #3569, fixes #3696
