d9df755e78 Fix value that is used before being initialised. 
This lead to a drive to not be considered as FAT32 despite it is
(or vice-versa).
Thanks to Damien Guibouret <damien.guibouret@partition-saving.com>.

a46d6637fa Use near pointers for printf()s where possible. Problematic is only the 
case where SS!=DS (which happens sometimes in resident code), in which
case va_list/va_arg need to use FAR pointers.
DS!=DGROUP never works, so I corrected that for NLS_DEBUG, by setting DS
in int2f.asm.

d8537c13ef Simplified truename(): eliminated the addSep state by adding a backslash in 
every new segment, including a trailing backslash. Simplified . and .. logic.
Converted switch to if because there were few cases left.

5ad1fd51e1 Use simpler code for copying the current directory constructing the "truename": 
instead of fmemcpy followed by strcpy, just use strcpy. Also use the near
TempCDS more.

9e1e01e9e6 If the current directory is no longer valid, call dos_cd() for the root to 
update the CDS cluster. Call media_check explicitly in truename() as a central
first and only place in directory-using DOS calls (except DosFindNext)
to call it.

95653072d3 The original DosGetCuDir is now inlined in truename(). DosGetCuDir now 
does truename("D:", CDS_MODE_SKIP_PHYSICAL), and this mode was changed
to no longer call QRemote_Fn (int2f/ax=1123).
