Raise robustness of call of dvipng command
* preview.el.in (preview-dvipng-command): Remove spurious quotes which
cause error for file names with space. (bug#31684)
(preview-dvipng-color-string): Replace single quotes with double
quotes for w32 users.
* doc/preview-latex.texi: (The preview images): Add warning that
(u)pLaTeX is not compatible with dvipng.
