Visual debug for vimL

[albfan]

Did you notice https://github.com/albfan/BreakPts can do visual debug for vimL?

I have use it on complex vim plugins succesfully.

Basically start a vim server:

$ vim --servername myserver

Then on another vim client

$ vi
:BreakPts
:BPRemoteServ myserver

Then you can define breakpoints from server or from client

Once debugging, on client:

:BPDWhere
:BPDNext
:BPDStep
:BPDEvaluate <whatever>

It relays on a trick about read client-server messages, but since it allows you to evaluate code, seems invaluable to debug vim.
