listp in above Lisp error gives a clue that a list is expected.

A describe variable confirms that it is indeed a list regexes.  Regex is
a Emacs regex and NOT a shell-regex.

,----[ C-h v revert-without-query RET ]
| revert-without-query is a variable defined in `files.el'.
| Its value is nil
| 
| Documentation:
| Specify which files should be reverted without query.
| The value is a list of regular expressions.
| If the file name matches one of these regular expressions,
| then `revert-buffer' reverts the file without querying
| if the file has changed on disk and you have not edited the buffer.
| 
| You can customize this variable.
