mix of vim9 and legacy vimscript

Hi Bram, Christian, Hi All,

I wish to use and port some part of plugin made by Christian few years ago in order to improve dirdiff with patience algorithm. https://github.com/chrisbra/vim-diff-enhanced

In vim9 help §2 it is written;

Vim9 script and legacy Vim script can be mixed.  There is no requirement to
rewrite old scripts, they keep working as before.  You may want to use a few
`:def` functions for code that needs to be fast.

So try to port the plugin, let some functions that need (...) or (A,L,P) args for commands that I don't know how to deal with in vim9script. https://github.com/niva-xx/vim9-diff-enhanced

And then test it,

:EnhancedDiff patience

I don't understant why I got this error in argue of s:Warn( which waiting for string arg.

function EnhancedDiff#Diff(...) #{{{2
  let cmd = (exists("a:1") ? a:1 : '')
  let arg = (exists("a:2") ? a:2 : '')

  " no-op
  " error occured, reset diffexpr
  try
    call s:DiffInit(cmd, arg)
  catch
    set diffexpr=
    call s:Warn( cmd . ' not found in path, aborting!' )

Thank you for your help

NiVa
