Environment

OS: Debian 10.9
age version: (devel) - 2021-05-18

Create public key file

What happened

rc@pxl:~/code/age$ ls -al ~/.age.key 
-r-------- 1 ryanc ryanc 189 May 18 11:25 /home/ryanc/.agekey
rc@pxl:~/code/age$ age-keygen -y ~/.age.key > ~/age.pub
Warning: writing secret key to a world-readable file.

I'm not writing a secret key here.

If I instead remove ~/age.pub and run age-keygen -y -o ~/age.pub ~/.age.key I do not get the warning.
