supply work dir parameter to term variable on Unix but not

[Konfekt]

On Win32 for s:term

vim-gtfo/autoload/gtfo/open.vim

Line 33 in 21a5e02

if s:iswin

the argument to open l:dir is added by gtfo

vim-gtfo/autoload/gtfo/open.vim

Line 156 in 21a5e02

elseif s:iswin && &shell !~? "cmd" && executable('mintty')

whereas on Unix it has to be added by the user

vim-gtfo/autoload/gtfo/open.vim

Line 195 in 21a5e02

silent call system(s:termpath." ".shellescape(l:dir))

How about opting for either one of these approaches for both OS's?
