+ * as possible:
+ *
+ * - Do not search the path if the filename already contains a path (either
+ * relative or absolute).
+ * (but do use path_ext)
+ *
+ * - If there's really only a filename, check the current directory for file,
+ * then search all path directories.
+ *
+ * - If filename specifies has *any* extension, search for the file with the
+ * specified extension first.
+ * (not necessary an executable one or one that appears in path_ext;
+ * *but* no extension or just a dot is *not* allowed)
+ *
+ * - If the literal filename is not found in a directory, try *appending*
+ * (not replacing) extensions from path_ext in the specified order.
+ * (an extension consisting of just a dot *may* appear in path_ext;
+ * unlike what happens if the specified filename ends with a dot,
+ * if path_ext specifies a single dot cmd.exe *does* look for an
+ * extension-less file)
+ *
+ * - The path variable may contain relative paths; relative paths are relative
+ * to the cwd.
+ *
+ * - Directories in path may or may not end with a trailing backslash.
+ *
+ * - Extensions path_ext portions must always start with a dot.
+ *
+ * - CMD does not trim leading/trailing whitespace from path/pathex entries
+ * nor from the environment variables as a whole.
+ *
+ * - When cmd.exe cannot read a directory, it wil just skip it and go on
+ * searching. However, unlike posix-y systems, it will happily try to run a
+ * file that is not readable/executable; if the spawn fails it will not
+ * continue searching.
