[bug-gettext] autosprintf and gettext mixed up manuals

[Max Polk]

There seems to be two projects whose manuals are collocated, causing 
broken links and some confusion.

From gettext - http://www.gnu.org/software/gettext/manual/gettext.html
* autosprintf link broken: << In C++: autosprintf "%2$d %1$d" (see 
Introduction)  >>

autosprintf - http://www.gnu.org/software/gettext/manual/index.html
* first link broken: << HTML (8K bytes) - entirely on one web page >>
* second link, then second link broken: << Class autosprintf: The 
autosprintf class >>

Maybe because the two manuals are deployed to the same "gettext/manual" 
place, they are getting criss-crossed.
