[Ovmsdev] <enter> not working with vfs edit?

[Mark Webb-Johnson]

Maybe the recent change for IDF v3 where Espressif messed around with CRLF.

2f0c9f0 Translate CR or CRLF to LF on async console for microrl

That should only affect the ASYNC console, I think. It converts CR/LF/CRLF -> LF. Maybe the enum KEY_ACTION in openemacs (vfsedit component) needs to change?

Fix is probably to add a NL=10 to KEY_ACTION and then to treat NL or ENTER as the same in the editor_process_keypress. My build environment is all switched to v3 at the moment, so hard for me to test (as IDF v3 does things differently). I’ve made the fix in the for-master branch, and it seems to work for me.

I just made the fix also in the master branch, but haven’t tested.
