+ * can be used before fork() to prepare to run a command using
+ * execve() or after execvp() to diagnose why it failed.
+ *
+ * The caller should ensure that file contains no directory
+ * separators.
+ *
+ * Returns the path to the command, as found in $PATH or NULL if the
+ * command could not be found.  The caller inherits ownership of the memory
+ * used to store the resultant path.
+ *
+ * This should not be used on Windows, where the $PATH search rules
+ * are more complicated (e.g., a search for "foo" should find
+ * "foo.exe").
