util.argparse: Fix bug (regression?) in argument parsing with --foo=bar After recent changes, '--foo bar' was working, but '--foo=bar' was not. The test had a typo (?) (bar != baz) and because util.argparse is not strict by default, the typo was not caught. The typo caused the code to take a different path, and bypassed the buggy handling of --foo=bar options. I've preserved the existing test (typo and all!) because it's still an interesting test, and ensures no unintended behaviour changes compared to the old code. However I've added a new variant of the test, with strict mode enabled and the typo fixed. This test failed due to the bug, and this commit introduces a fix.
