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

I put in a \r to \n translation in the async console similar to what
has been present all along in the telnet and ssh consoles. I made
this change because in the esp-idf v3.0 there is a new behavior for
stdin line endings. In the config there are additional lines to choos
the stdin line ending:
This defaulted to CR which resulted in the async console never seeing
a newline input so it was not possible to execute commands. It did
not matter whether Ctrl-J or Ctrl-M is pushed on the keyboard, still
the character coming through was CR.
Unfortunately, changing the config to LF or CRLF did not seem to make
any difference. It appears that the compiled code does not change
with this parameter, so my guess is that it is supposed to affect the
behavior of the python code. I believe the python code is where the
character translation is occurring because when I tried "make
simple_monitor" then it looks like both CR and LF were delivered to
the console. I tried my own console program that I wrote a while ago;
it translates Enter to newline before sending it through, so then the
console received the newline that it wants and responded properly.
After discussing with Mark, we agree to fix the problem by having the
async console translat CR to LF. You could argue that this was not
fixing the problem in the right place since the change in behavior
that prompted the change was apparently in the python monitor program.
