+Some regex libraries assume that the text given is null terminated, while
+others require the length be given as a separate parameter. Therefore for
+maximum portability assume that {\it text} cannot contain embedded nulls.
+
+When the {\it Matches(const wxChar *text, int flags = 0)} form is used,
+a {\it wxStrlen()} will be done internally if the regex library requires the
+length. When using {\it Matches()} in a loop
+the {\it Matches(text, flags, len)} form can be used instead, making it
+possible to avoid a {\it wxStrlen()} inside the loop.
