-e and permission denied

[victor]

-e will return file not exists, even if it does, when permission denied error 
happen. I am wondering if this documented/correct behaviour or no.

this behaviour seems poorly documented in manual
http://www.gnu.org/software/bash/manual/bash.html

but butter documented here
