bug#27445: 26.0.50; Insufficient documentation for pinentry.el

[diego]

I see pinentry.el was removed from emacs master - is it worth mentioning it did 
more than the functionality stated as making it obsolete?

For example, as long as INSIDE_EMACS was set, I could decrypt files using gpg 
from eshell or term and be prompted through the minibuffer, and git could sign 
commits while prompting through the minibuffer as well. 

I guess I'm saying it seems to me that pinentry.el had more use than just being 
used by epa.
