Hi Jean and all,

Experience 2: name it as abc def ghi.tex (so it includes spaces in filename)

Ask to generate previews for all document.
Answer YES to "Cache preamble?"
It **appears to work** but in fact it doesn't:
....
Running `Preview-DviPNG' with ``dvipng -picky -noghostscript abc\ def\ ghi.dvi -o
"abc\ def\ ghi.prv/tmp14749czs/prev%03d.png" -D186 ''
This is dvipng (dvipng (TeX Live)) 1.15 Copyright 2002-2015 Jan-Ake Larsson
[1 (preview-latex version 12.1) (preview-latex tightpage option detected, will
use its bounding box)
dvipng: Fatal error, cannot open output file abc\ def\
ghi.prv/tmp14749czs/prev001.png
Confirmed. It seems the reason is that `preview-dvipng-command'
contains spurious quotes. Various `preview-*-command' are defined as:
(defcustom preview-dvipng-command
"dvipng -picky -noghostscript %d -o \"%m/prev%%03d.png\""
...
(defcustom preview-dvips-command
"dvips -Pwww -i -E %d -o %m/preview.000"
...
(defcustom preview-fast-dvips-command
"dvips -Pwww %d -o %m/preview.ps"
...
(defcustom preview-pdf2dsc-command
"pdf2dsc %s.pdf %m/preview.dsc"
...
. They don't have quotes around %m except `preview-dvipng-command'.
Removing the quotes makes dvipng works with file name with space on my
side.
In addition, I noticed during test runs that single quotes in
`preview-dvipng-color-string' choke dvipng on w32 platform because
single quotes are not consumed by w32 shell (cmd.exe).
Could you please test the following patch? (It is for preview.el.in in
the source files, not for preview.el.)
I confirm problem is fixed at my locale for the MWE I posted initially:
(mac os x 10.9.5)
Here is transcript:
...
(see the transcript file for additional information)
Output written on "abc def ghi.dvi" (1 page, 1584 bytes).
Transcript written on "abc def ghi.log".

My testing does not extend to that part of your patch dealing with options
but I trust it does the right thing...
Best,
Jean-François
