  * LocalizePathHead() -- Make path relative to local part

- * ConstructLocalPath takes a path  and a directory that path should

- * for   a prefix  that represents a canonical path.  If such a prefix
- * is found,  the path is adjusted to remove the prefix and the path

+ * ConstructLocalPath takes a path and a directory that path should
+ * be considered relative to.  There are two possible cases:
+ *
+ * The path is an absolute path.  In this case, the relative path
+ * is ignored.  We check the path for a prefix that represents a
+ * canonical path, and if one is found, we adjust the path to remove
+ * the prefix and adjust the directory to which it should be
+ * considered relative to be the local version of that canonical path.
+ *
+ * The path is a relative path.  In this case, we check to see if the
+ * directory to which it is relative represents a canonical path, and
+ * if so, we adjust that directory to be the local version of that
+ * canonical path.  The relative path itself is left unchanged.
