Are you sure you have written exactly what you want? If you assume files is
['a', 'b'] and these files exist,
:execute 'grep' fnameescape(join(files))
will not work, neither will work correct
:execute 'grep' shellescape(join(files), 1)
: both will try to use a single file named `a b`.
You need
:execute 'grep' join(map(files, 'shellescape(v:val, 1)'))
