Eval variables on lower backtrace level not working

[albfan]

After remote_send backtrace level is restarted to topmost so variables from lower level are not avaliable.

Maybe a vim editor fix is needed. Investigate

tested on https://github.com/vim/vim/issues/2237#issuecomment-341970099

it should work now.

function! Bar(argBar1, argBar2)
  let c = 6
  return a:argBar1.' '.a:argBar2  ##stop here
endfunction

function! Foo(argFoo1, argFoo2)
  let c = 5
  let b = Bar(a:argFoo1, a:argFoo2)
  echo b.' '.c
endfunction

Stopping on Bar function after let c = 6

breakadd func 2 Bar

executing BPDUp

vim-breakpts fails with:

c: (ERROR): Vim(let):E121: Variable sin definir: a:level in function Foo[2]..Bar[2]..breakpts#ToJson, en la línea 3

but

echo remote_expr('MYSERVER', 'c')

works in any frame
