I think you need to take a good look at Emacs sources to understand
what is meant by ``name-prefixes that follow a uniform convention'' ;-).

Emacs sources use the_lower_case_with_underscores for naming functions
and variables.  They use upper-case letters in functions and variables
which have special meaning.  For example, each primitive whose name in
Lisp is primitive-function is defined in C as Fprimitive_function, and
each variale known in Lisp as built-in-variable is defined in C as
Vbuilt_in_variable.

These F and V prefixes are certainly following a uniform convention.

Err... what do you see in demangle.h that is pertinent to the above
issue?  I don't see anything except that they use lower case for
enums, which AFAIK is quite a wide-spread habit, including in Emacs.
