use test(1) -eq and -ne to compare integers, and reduce quoting
This brings the rest of the regression test scripts in line with patch.sh.
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()
