- add WRAP_AUTO and WRAP_TERM (for terminal emulator)
WRAP_AUTO wraps lines if the window is more than 3/4 of the screen width
if window is narrower, lines are truncated.
WRAP_TERM does not display the \ wrapping mark to simulate terminal behavior
- add default_wrap member in ModeDef structure
- delegate to view pane for man, ssh and compile commands
- rename method dispatcher `text_display` as `display_line`
rename corresponding mode based handlers as `xxx_display_name`
- rename method dispatcher `text_backward_offset` as `backward_offset`
- add default text handlers for `move_bof` and `move_eof` in
hex, binary and unihex modes
- handle utf-8 in window prompt (ex: default buffer name for C-x b)
- add various TODOs
* always regsister callbacks on s->top and s->top_offset
* handle saved_data generically, remove window callback
this will be replaced with view history mecanism.
* mode initializers should call text-mode-init to register ccallback
for s->offset and s->top_offset, and other generic stuff.
* this is error prone, should simplify this with base_mode property and
keep unmapped windows lingering to get rid of ModeSavedData handlers
* pass ModeDef pointer to mode_probe functions
* add extensions field to mode structure
* rename ascii mode to binary mode
* rename mode variables and fields to more specific names
renamed canonize to canonicalize
added crude support for ~user -> /home/user
added win32 specific stuff in basename
added C-/ as an alias for C-_
some cosmetics, moved code
create files with mode 0644 in raw_save_buffer
untabified, removed redundant spaces
modified code generators to the same effect
