read-buffer-completion-ignore-case

[Drew Adams]

There is no real use of `read-buffer-completion-ignore-case' in the Emacs Lisp
files, and I haven't bothered to download the C source code to check all the
places it might be used (besides `read-buffer').

Question: How can Emacs-Lisp code know whether completion involves buffer names?


Suppose I want to do something depending on the value of
`read-buffer-completion-ignore-case', but only when completion is for buffer
names - how can I test that? It's relatively easy to test for file-name
completion, but how to do that for buffer-name completion?
