+REQUIRES: shell
+
+This tests that we abstract two peculiarities of unix in can_execute:
+
+* Directories are executable, but we don't want to try to execute them.
+* For shell scripts, we also need to be able to read them.
+
+The PATH is constructed such that 'not' will first find a directory named
+TestProg, then a file with executable bit but not readable and finally a
+shell script which always returns false, which is what it actually tries to
+execute.
+
+If we want, it is probably OK to change the semantics of can_execute and this
+test, but for now this test serves as a reminder to audit all the callers if
+we do that.
