Can hglock set file permisions?

[Friedrich Hagedorn]

Hello,

Im playing around with the new hglock extension 
(https://bitbucket.org/aragost/hglock) and was wondering that
no file permissions where set for locked files. So I can
edit locked files but can not commit these locked files. I
think it would be better if I even can not modifed locked
files because of their readonly file permissions.

Is it possible to implement this?

Thanks,

  Friedrich
