I asked this in the channel, but no-one was able to answer, so I'm asking again here:
Is it possible to define an abbreviation that is case sensitive (not a dynamic one)? I found that dabbrev-case-fold-search didn't seem to be what I was looking for.
The motivating example for me was that I wanted "true" to expand but "True" not to.
(Pardon me if my terms are not exactly right yet; I'm still relatively new to emacs.)
