since 4.12 'info gettext' opens libc.info

[Benno Schulenberg]

Hi all,

Since texinfo-4.12 'info gettext' no longer opens the main page of 
gettext.info for me, but opens libc.info instead, on the node 
'Translation with gettext', "8.2.1.1 What has to be done to 
translate a message?"  Is this a bug in my system, or in texinfo?

Other documents (gawk, grep, sed, ...) still open on their main 
page.  It's just for gettext that the behaviour changed with 4.12.
('info tar' has always opened on the node 'tar invocation' -- is 
that intentional?)

Benno
