1. `imenu--generic-function' should not have a double-hyphen in its
name. It is the main function in the library, and it is explicitly
referenced by multiple doc strings in the file, including that of a user
option (`imenu-generic-skip-comments-and-strings') and that of the
principal configuration variable (`imenu-generic-expression'), which is
defined per mode. The function should be renamed to
`imenu-generic-function', and the old name should be deprecated.
2. The doc string of `imenu--generic-function' says this, with zero
description of INDEX-NAME INDEX-POSITION FUNCTION and ARGUMENTS:
The return value is an alist of the form
(INDEX-NAME . INDEX-POSITION)
or
(INDEX-NAME INDEX-POSITION FUNCTION ARGUMENTS...)
The return value may also consist of nested index alists like:
(INDEX-NAME . INDEX-ALIST)
depending on PATTERNS.
Each of those pieces of the return value should be specified, not just
named.
3. Similarly, other functions and variables should be renamed to use a
single, not a double, hyphen, starting with `imenu--sort-by-name' and
`imenu--index-alist'. I don't argue now that NO functions wnd variables
in the library should have names declaring that they are internal, but a
better judgment call is in order.
They too are referenced from other doc strings. For example, the doc
string of `imenu-sort-function' says to look at `imenu--sort-by-name'
for an example of a sort function. And the doc string of autoloaded
variable `imenu-create-index-function' refers to `imenu--index-alist'
for the format of the buffer index alist.
We are documenting the structure and behavior of Imenu by referring to
"internal" variables and functions. That makes no sense - or rather, it
points out how silly was declaring these to be "internal".
