It is not very quick, since the code has to reread all Info subfiles
(its slowest part). When the delay after typing `T' is more than 1 sec,
this is unbearable for many users. So we could cache the TOC buffer per
Info file, if this costs us nothing. I see one problem: how to refresh
the cached TOC buffer when the Info file changes - the usual key `g'
for buffer refreshing is already allocated to `Info-goto-node'.
