{\it Flags} may be combination of {\tt wxRE\_NOTBOL} and {\tt wxRE\_NOTEOL}.
System regex libraries always assume the text being searched is null
terminated and any length given is ignored.
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 using the built-in regex library, the first overload obtains the length
of the string using wxStrlen, the second from the {\it len} parameter and the
third from the length of the {\it wxString}.
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.
