In cygwin /etc/hosts is a symbolic link to
C:\WINDOWS\system32\drivers\etc\hosts
and if expanded in that way is not recognized as a full path because
does not start with / or with ~.
The small patch change it in posix format
/cygdrive/c/WINDOWS/system32/drivers/etc/hosts
so it is recognized as a full path and the .swp file
is created (in the other case there is the
message "*E303* Unable to open swap file")
Maybe the mch_FullName() is a better place to put the
cygwin_conv_to_posix_path().
I have put it there because there is also
slash_adjust() for other platform.
