Subject: bug#41268: [PATCH 6/9] Drop unnecessary backward compatibility aliases

From: Jonas Bernoulli <[email-masked]>
Date: Thu, 14 May 2020 21:13:22 +0200

* lisp/epa-file.el (epa-file--encode-coding-string,
  epa-file--decode-coding-string): Remove aliases for
  encode-coding-string and decode-coding-string.

* lisp/epa-file.el (epa-file-write-region): Use encode-coding-string
  instead of removed epa-file--encode-coding-string.

encode-coding-string and decode-coding-string existed every since
4ed4686978bd18292e2bb7b87a7b0e0407ecb3b1 added them in 1997.
