FYI, I've added a new user option completion-preview-ignore-case on the
master branch (commit f1794a17b62), which controls case sensitivity for
Completion Preview mode specifically.  This is definitely safe to set
buffer-locally.  The docstring of this new variable should hopefully
also explain exactly what's the expected behavior in this regard.


Cheers,

Eshel
