fix illegal reference to a destroyed variable
The char array 'dash_o' is an automatic variable. The string "-o" is copied into this array.
Later the address of the array dash_o is assigned twice to lpargs[++i].
After leaving the block, the array dash_o is gone and lpargs[...] contains an illegal reference.
This was discovered in a release mode when compiled with gcc version 4.7.2
Patch doesn't apply for Qt5 where 'lpr' support has been removed.
