Patch which helps with quoted lpFile in some cases

This patch changes SHELL_execute so that it keeps track of whether the value in
wszApplicationName is known to contain a singular value -- one which should not
be parsed as if spaces might separate a program from parameters.

The main case where this is known is when lpFile is quoted on input.  Without
this patch, SHELL_execute unquotes the filename but forgets that it was quoted
and later tries to parse it as a command line.	The original quoting should
prevent such parsing.
