This version fixes a regression with regard to tradtional behavior of the non-standard FreeBSD option "-e". In the previous version "-e quit" caused bc to exit before any computations had been performed, since all -e option parameters were concatenated and parsed as a whole, with quit causing the program to exit as soon as it was parsed. This version parses and executes commands passed with -e one by one and only exits after all prior commands have been executed. This commit is not a SVN merge, since the vendor import had been performed after the import to contrib. Instead the contents of contrib/bc has been removed and the new version is copied over unchanged from vendor/bc/dist.
