printer-name is expanded to a file name on a local drive;
sometimes printing a file loaded from a network volume fails.
(direct-print-region-function): Add a function to
write-region-annotate-functions to append a formfeed character to
the region being printed, if the region doesn't end with a
formfeed already. This avoids creating a second print job
containing a blank page when print spooling is enabled on Windows.
(find-buffer-file-type-coding-system): For reading a file,
check for binary file, then text file, then existing file,
then whether file name is translated.
(find-buffer-file-type-coding-system):
For writing, use buffer-file-coding-system if set, otherwise
buffer-file-type.
(find-file-not-found-set-buffer-file-coding-system):
Renamed from find-file-not-found-set-buffer-file-type.
Set buffer-file-coding-system as well as buffer-file-type.
(find-binary-process-coding-system, find-buffer-file-type-match):
New functions.
(find-buffer-file-type): Use find-buffer-file-type-match.
Add find-buffer-file-type-coding-system to file-coding-system-alist
as the default entry.
Add find-binary-process-coding-system to process-coding-system-alist
as the default entry.
