Untabified info/dir breaks dir file parsing in info.el

[David Engster]

The file info/dir was untabified, which seems to break parsing of the
dir file in Emacs. When I do

INFOPATH=<YOUR PREFIX>/share/info emacs -Q

and then M-x info (on a current checkout), I get the error "No such node
or anchor: Top". This is due to `Info-following-node-name' depending on
a tab between "Node: Top" and the following description. So I guess the
tab should be either put back in, or `Info-following-node-name-re' must
be adapted to handle spaces between node name and description.
