[Bug] Issues with format.el: coding system, byte/char confusion |

[Test using Emacs-21.2.95.1, with head revision of: format.el,v 1.40,
fileio.c,v 1.479]
There are some issues with format.el:
1. Shouldn't `format-annotate-function' also save the buffer-local
variable `buffer-file-coding-system' (as it does with
`selective-display' and `enable-multibyte-characters' since v1.38)?
2. To compute the coding system of the current buffer, Emacs adds
function `after-insert-file-set-buffer-file-coding-system' to
`after-insert-file-functions'. Is this correct?
In the DEFUN for "insert-file-contents" in fileio.c, Emacs first
calls Qformat_decode and then the functions in
`after-insert-file-functions'. In other words, we have the
following call sequence:
- decode functions using format.el,
- decode functions in `after-insert-file-functions' before
`after-insert-file-set-buffer-file-coding-system',
- Emacs determines the coding system with
`after-insert-file-set-buffer-file-coding-system',
- decode functions in `after-insert-file-functions' after
`after-insert-file-set-buffer-file-coding-system'
I would assume that the coding system must be determined before any
of the decode functions have been executed... Or does it simply not
matter when `after-insert-file-set-buffer-file-coding-system' is
called?
3. The docstring of `after-insert-file-functions' includes "It should
return the new byte count", whereas `format-decode' returns the
new char count.
In the DEFUN for "insert-file-contents" in fileio.c, the invocations
of Qformat_decode and the functions in Vafter_insert_file_functions
(and the use of the return value `inserted') look quite similar...
Which is correct for both: byte count or char count? (I hope the
latter, you might want to check
`after-insert-file-set-buffer-file-coding-system' in this case.)
