 // Set up a filter for a Save/Open dialog, which will consist of |file_ext| file
 // extensions (internally separated by semicolons), |ext_desc| as the text
 // descriptions of the |file_ext| types (optional), and (optionally) the default
 // 'All Files' view. The purpose of the filter is to show only files of a
 // particular type in a Windows Save/Open dialog box. The resulting filter is
 // returned. The filters created here are:
 //   1. only files that have 'file_ext' as their extension
 //   2. all files (only added if 'include_all_files' is true)
 // Example:
-//   file_ext: { ".txt", ".htm;.html" }
+//   file_ext: { "*.txt", "*.htm;*.html" }
 //   ext_desc: { "Text Document" }
-//   returned: "Text Document\0*.txt\0HTML Document\0.htm;.html\0"
+//   returned: "Text Document\0*.txt\0HTML Document\0*.htm;*.html\0"
 //             "All Files\0*.*\0\0" (in one big string)
 // If a description is not provided for a file extension, it will be retrieved
 // from the registry. If the file extension does not exist in the registry, it
 // will be omitted from the filter, as it is likely a bogus extension.
