Hi, all I'm using mew --- a package of emacs plugin. It's info docs has the following lines:
======================================================= START-INFO-DIR-ENTRY * Mew: (mew.info). Messaging in the Emacs World. END-INFO-DIR-ENTRY ======================================================= in install-info version 4.12, the tool does not parse the entry correctly, in file dir, the install-info insert many space, so the (mew.info) becames (mew. info), and the info can't find the correct entry. But in version 4.9, the install-info works fine. I don't know whether it is a bug of texinf or the Mew package. But it seem it is more likely your bug, not the Mew. Any reponse? cheers!
