bug#19091: 24.4; help autocompletion glitch

[Emanuel Berg]

I wrote about this on gnu.emacs.help - this is part of
what I wrote:

Hit `C-h f' and type "gnus-summary--reset", then
strike `M-b' and hit TAB. Now it says
"gnus-summary--invreset", so hit RET.

    gnus-summary--invreset is an alias for
`gnus-summary--invreset', which is not defined. Please
make a bug report.

Of course, there is no gnus-summary--invreset
(deadlock) alias (but there is a `gnus-summary--inv')
so that's a bug I won't report...

I have seen such messages before so I suppose it is a
well-known bug (I'll report it just the same) but I
thought I'd mention it when I suddenly came a across
an example that is reproducible enough.

(This bug report unfortunately got no response at the time.)

I get:

user-error: Symbol’s function definition is void: gnus-summary--invreset

Which seems correct to me, so I'm going to go ahead and guess that this
bug has been fixed in the years since it was reported, and I'm closing
this bug report.

If this is still a problem, please respond to the debbugs address, and
we'll reopen the bug report.
