eyaml edit should produce evenly folded blocks.

[pillarsdotnet]

From eyaml edit testfile.eyaml, I typed:

File Edit Options Buffers Tools Help
# | This is eyaml edit mode. This text (lines starting with # | at the top of
# | the file) will be removed when you save and exit.
# |  - To edit encrypted values, change the content of the DEC(<num>)::PKCS7[]!
# |    block.
# |    WARNING: DO NOT change the number in the parentheses.
# |  - To add a new encrypted value copy and paste a new block from the
# |    appropriate example below. Note that:
# |     * the text to encrypt goes in the square brackets
# |     * ensure you include the exclamation mark when you copy and paste
# |     * you must not include a number when adding a new block
# |    e.g. DEC::PKCS7[]!

When I view the resultant testfile.eyaml, I see:

Notice that the first line is exactly ten characters longer than the rest, probably because the line-wrapping code doesn't account for the initial ENC[PKCS7, prefix. I would prefer that lines be wrapped consistently, like this:

I can hand-edit the encrypted text to produce evenly-wrapped lines, but subsequent changes via eyaml edit will restore the hanging outdent.
