This method supplies a list of file extension filters formatted for a Save As dialog box. The extensions are formatted in pairs of descriptions and extensions, with each element separated by newlines. For example, a set of filters for C++ and C# files might formatted as "C++ files (*.cpp)\n*.cpp\nC# files (*.c#)\n*.c#\n". Visual Studio always prepends the filter list "All Files (*.*)\n*.*\nText Files (*.txt)\n*.txt\n" to whatever is returned from this method.

The base method calls LanguageService.GetFormatFilterList and replaces all vertical bar characters ("|") with newlines. The base method also insures the returns filter list is terminated by a newline. This method is an implementation of IVsFormatFilterProvider.GetFormatFilterList.
