I was going through the old "todo" things and bumped into the completion
in Info-index. So it's now finally working.
But I'm still wondering about the thing that I brought up a year ago:
The function info-insert-file-contents is called twice in info.el, once
with the `visit' argument set to t and once to nil (by default).
I can't quite figure out why there is such a difference, but the result is
that if you visit the `emacs' manual, `buffer-file-name' is nil while
if you visit the `message' manual, `buffer-file-name' will be set to
the path corresponding to the info file (like "/usr/local/info/message").
The difference being that `emacs' has a separate tag-table-only file
while `message' does not.
I don't really mind the discrepancy as much as I dislike setting
buffer-file-name since it has several side-effects:
- when visiting the `message' info pages, if you do
C-x C-f /usr/local/info/message RET you're put into the *Info* buffer.
- if you use uniquify and (setq uniquify-after-kill-buffer-p t),
the *Info* buffer will be renamed "message" if you kill another buffer.
Now the C-x C-f thing might be considered a feature (especially if
we might want to automatically turn on info-mode when visiting info
buffers at some point in the future, using something like
Info-on-current-buffer). But the interaction with uniquify is
rather unfortunate.
Should uniquify be instructed not to muck around with Info buffers
or should Info be careful not to set buffer-file-name ?
I've been running with the trivial patch below for a year now
without seeing any adverse effect.
