Most extension allow only for a boolean value so the current behaviour of just sending the extension with a trueish value is fine. However, some extensions that we could eventually support (like "objectformat") have a string value. This is a preparatory step towards that. ok stsp@

This behaviour is already documented in got-worktree(5) but wasn't actually implemented. ok stsp@

The fix for CVE-2022-39253 in Git made our regression tests fail since creating submodules from local clones is no longer allowed by default. Add an override to our invocations of "git submodule add", the same which was added to Git's regression test suite as part of their fix. This CVE doesn't otherwise affect us. We do not implement submodules. Our use of them in regression tests exists only to ensure that Got does not freak out when it sees one. Precisely because automated support for nested repositories and/or working copies (as in Git Submodules, or Subversion Externals, etc.) have been an endless source of security problems in other systems. sudden test failures pointed out by naddy@

This brings the rest of the regression test scripts in line with patch.sh.

Escape sequences are not handled by every echo(1), e.g. not on FreeBSD. '?' is a glob character and must be quoted. '!' is not a shell meta character. ok tracey stsp

Previous default output remains when test cases are run individually. ok tracey

We should not resolve a symlink target path recursively when installing a symlink in the work tree. We want to handle this symlink's target, not the end result of following a chain of symlinks in case such links already exist.
