Issue with symbolic links

[narcisse81]

When opening a symbolic link on a file, vaffle actually opens the file resolved by the normalize-path function. And I don't think that it is really wise.
I would prefer to edit the link which is local.
To avoid troubles, I had to modify the vaffle#util#normalize_path function:

function! vaffle#util#normalize_path(path) abort
if a:path ==? '/'
return '/'
endif

let result = resolve(a:path)
if !isdirectory(result)
    let result = a:path
endif

" Remove trailing path separator
return (match(result, '\(/\|\\\)$') >= 0)
            \ ? fnamemodify(result, ':h')
            \ : result

endfunction

With this modification, it the result of the resolve function is a directory, the behavior is as in the original version. If it is a regular file, then one keeps the original path.

Best regards
