Update the Vim script functionList

 commentExpr
 -----------

 * the UDL targets "legacy" Vim script, in which comments begin with a
   double quote ("), not a hash (#) as in Vim9 script [^1]

 mainExpr, nameExpr
 ------------------

 * allow "namespaced" functions like those encountered in many Vim
   plugins. The conventional pattern is `<vim_script_file_name>#<func_name>`,
   assuming `<vim_script_file_name>` can be found on the file system.
   Any sub-directories must also be part of the name, similar
   to a Java package, e.g.,

    <root_dir>#<sub_dir>#<vim_script_file_name>#<func_name>

   A namespaced function cannot be qualified with `s:` because the
   auto-generated script id of a "private" function makes the name differ
   from the name of the file or directory on disk

 * end the function name pattern with `\w*` instead of `\w+` to allow
   single-letter function names
