shell code fixes
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
add a -q option to tests for quiet output and use it for 'make regress'
Previous default output remains when test cases are run individually. ok tracey
stop using realpath(3) to resolve a symlink target in install_symlink()
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.
