Is there a check, e.g. optional, for whether a given character cdr
for a `prettify-symbols-alist' entry is, as the only char in a
symbol name, either `fboundp' or `boundp', before going ahead and
prettifying the symbol that is the cdr of that alist entry?
IOW, check whether, e.g., for an entry such as `("not" . ?¬)',
(boundp '¬) or (fboundp '¬)?
A cursory glance at the code didn't find such a check. Seems like
it might be a good thing to add. If `¬' already exists as a
function or variable, then you probably do not also want
occurrences of the symbol `not' to be shown as `¬'.
IOW, if the only guard for prettifying is `prettify-symbols-alist'
then there could be cases of symbol-appearance capture. Sure,
this would not be common, and sure, someone could turn off the
mode if it is noticed. But it might also be good to make such
a check available (optional).
