This release changes the osh exit status for alias and unalias so that they exit with a false (1) status when there are no aliases to print, set, or unset. Otherwise, they exit with a true (0) status when there is no error. It adds 'version' as an osh special built-in command, replacing the previous 'version' alias found in examples/dot.oshrc. It changes the _XOPEN_SOURCE definition from 600 to 600L in mkconfig. It also adds DEBUG_ALIAS, DEBUG_GLOB, and DEBUG_PROC definitions (undefined by default) to err.h for printf debugging.
