Hmm... so we have a problem.  BTW, you don't need the above, you can
just do the following for a test:

          (when t;;pcomplete-ignore-case
            (setq table (completion-table-case-fold table)))

Or alternatively set pcomplete-ignore-case to t.  And indeed, in my test
it did not make the completion case-sensitive.

But fixing it with a new command isn't right, because
completion-at-point is called from various places.

It looks like the core of the problem is that completion-table-case-fold
doesn't work.

For the emacs-25 branch, the better fix is probably to set
completion-ignore-case to t buffer-locally in ERC's major mode.
