completion problems

[Sam Steingold]

the current cvs head appears to have a problem with completion.
when I have a file (or buffer) named foo.bar and I type "foo." and hit
TAB, the cursor moves 1 step to the left (i.e., between "o" and ".")
instead of completing to "foo.bar".
this happens with "-" instead of "." too.

I don't see anything suspicious in ChangeLogs...

does anyone observe this too?

It works ok when I try it.
I used a directory with no other files that start with `foo'.
I just updated from the sources right before.

I have 3 files:
config.h.in
config.h.in~
configure.in

C-x C-f c o n TAB

==> completed to "config", cursor right after "g" (correct)

then
. TAB

*Completions* buffer pops up with the 3 files above,
and cursor is now between "g" and "." (incorrect, I expected a
completion to "config.h.in").

Is this in `emacs -q --no-site-file' ?
The behavior you see reminds me of partial-completion-mode.

Why not just "config"?

indeed turning partial-completion-mode off "fixed" the problem.
so now we know what is broken - it is partial-completion-mode,
not the main completion.
(I have had partial-completion-mode enabled for 2+ years and I have
not experienced this weirdness until very recently).

because "config." should complete to "config.h.in" in a directory with 3
files listed above.

thanks for your help!

There is no specific maintainer for complete.el, and I have never
studied that code myself.  Who would like to debug this?

I see no bug.  Just a behavior that Sam didn't expect.

Well, I won't complain that it isn't a bug ;-).
