 {{{
 convmv --lower --notest --replace FILE
 }}}

 deletes 'FILE' instead of renaming it to 'file'.
 I believe this is because convmv overwrites files by deleting the output
 file first, then renaming the input. This can cause problems on case-
 insensitive file systems. The attached simple patch removes file deletion
 before renaming.
