*** ../vim-7.1.156/src/ex_docmd.c Sun Nov 11 19:16:44 2007

}
/* ignore comment and empty lines */
! if (*ea.cmd == '"' || *ea.cmd == NUL)
{
ex_pressedreturn = TRUE;
goto doend;
--- 1741,1749 ----
}
/* ignore comment and empty lines */
! if (*ea.cmd == '"')
! goto doend;
! if (*ea.cmd == NUL)
{
ex_pressedreturn = TRUE;
goto doend;
