[Toybox] [PATCH] vi: small fixes.

[Jarno Mäkipää]

I apologize for potentially being responsible of destroying config
files on your device :-)

Happy to hear someone already tried to use it. There will be some
problems with files that has non UNIX line-endings also tabs will be
replaced by spaces etc...
But for task like changing variable or commenting out few lines it
might come handy when there is nothing else available.

I'm trying to find time and motivation to continue working on this,
now as the summer has past.
