(gitignore) all .quicklisp-path file is ignored
improvement: the argument to cim_home is now optional (cim_home) = $CIM_HOME/
separated shebang-p and added a unit test
package conflict (remove osicat)
use optional argument of cim_home
Modified teh test case: on ccl, string= is not implied.
Fixed shebang-load on ccl.

On ccl, remove-shebang does not work because it still loads the original pathname,
not from the concatenated stream.
