It looks a bit like msys perl could be recognising
"server:/home/pgrunner/..." and converting it to
"server;C:\tools\msys64\home\pgrunner\...".  From a bit of light
googling I see that such conversions happen in msys perl's system()
unless you turn them off with MSYS_NO_PATHCONV, and then we'd have to
do it ourselves in the right places.
