Hi Omar,

thanks for this report.  I can reproduce this on Windows.  Before
patching `TeX-expand-list-builtin', I would like to know if people can
reproduce this on other OSes than windows.  Another idea would be to add
something like this to your init file:

    (setq TeX-view-program-list
          '(("SumatraPDF"
             ("SumatraPDF -reuse-instance"
              (mode-io-correlate " -forward-search \"%b\" %n") " %o")
             "SumatraPDF")))

Note the quotes around %b.  It fixes the issue only for SumatraPDF
without touching the rest.

Best, Arash
