--env-file doesn't support inline comments #4404

Description

Currently docker run --env-file someenvfile.env sometag doesn't remove inline comments -- so if something like SOMEVAR=somevalue # comment is written, SOMEVAR is set to somevalue # comment instead of somevalue.
Similar issue for Docker Compose was fixed about 1.5 years ago.

Reproduce

  1. echo 'SOMEVAR=somevalue # comment' > test.env
  2. docker run --env-file test.env bash bash -c 'echo $''SOMEVAR'

Expected behavior

somevalue is expected but somevalue # comment is actual.
