[setup - the official Cygwin setup program] branch master, updated. release_2.883-4-g2782008

commit 27820085c4a706d9c59a7faae1ac9efa1c0b3cba
Author: Ken Brown <kbrown@cornell.edu>

    Throw exceptions instead of exiting with error codes
    
    There were two places in PickView.cc and one in choose.cc where setup
    would silently die with an error code.  Change this so that setup now
    throws exceptions.  The exceptions are caught by
    TOPLEVEL_CATCH("DialogProc") in PropertyPage::DialogProc().
