What's the purpose of this `provide' call? I've downloaded emacs-23.4.tar.gz from ftp.gnu.org. The only place where hashtable-print-readable occurs in code (including C) is the above occurrence in subr.el. And I don't see any reason why third party code should want to test for such a feature. So, why is it provided at all? Just curious... Regards, Michael. ^ permalink raw reply [flat|nested] 4+ messages in thread
