wcmd: strip quotes around executable and retry on error

wcmd: strip quotes around executable and retry on error
wcmd currently gives a 'File not found' error for the command:
`./wine wcmd /c "notepad test.txt"` because it only tries to execute the
program "notepad text.txt". In XP, cmd.exe starts notepad.exe with test.txt as
its argument upon not finding a "notepad text.txt" executable.
