Hi Jean and all,

The proposed method, with slight modification explained below, works for
all the cases I tested.  Thank you again!
For now, I attach the patch for preview-latex part only so that the
reader can concentrate on the relavant changes.

AUCTeX always runs TeX commands after changing the current directory to
that of the master file, so forward slash would never appear as an
argument of the command.  The region file is created in the same
directory as the master, thus region compilation should work as well.

I tried removing those quotes and let the quotes added around the file
name with space to be put inside /AUCTEXINPUT like this:
pdflatex -foo -bar &prv_ppp_qqq /AUCTEXINPUT{"ppp qqq"} (without escape for 
, because it's easier to absorb the difference in the way of quoting the
shell arguments between w32 and non-w32 platforms.  Experiments showed
no problems even for files without space, so the attached patch takes
this way.  If this has any shortcomings, please tell me.
