Fixes #407

hi @ejoffe , any chance to get the feedback on this ? thanks.

Sorry about the delay. Looks good to me.
One nit: is there a better check to see if it's cygwin instead of checking the HasPrefix equal to cygdrive? this seems fragile.

Hi @ejoffe

is there a better check to see if it's cygwin instead of checking the HasPrefix equal to cygdrive? this seems fragile.

within shell scripts, the check would typically be based on uname -a command output - but apparently this won't work if spr is running in plain CMD environment. So i didn't want to overcomplicate the implementation which i won't be able to test anyway, because my cygwin paths all start with /cygdrive

@ejoffe any chance to get this merged ? 😅
