- 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
- add EditState *qe_split_window(EditState *s, int prop, int side_by_side);
takes proportion and direction
- set-trace splits the current window 75/25
- add start-trace-mode
terminal emulator:
- add EditState.cols and EditState.rows: window dimensions in characters
- pass target window to new_shell_buffer()
- use window size for shell terminal emulator initial screen size
- set COLUMNS and LINES environment variables for child processes
- factorize emulator character output
- increase number of CSI arguments
- simplify and improve CSI m argument processing including
multiple argument sequences
- minimal support for `:` as argument separator eg:
\033[38;5;128:128:128m
- support erase line vt100 command:
\033[K, \033[0K erase end of line
\033[1K erase beginning of line
\033[2K erase complete line
debugging:
- pass string argument to set-trace: on, off or list of trace indicators
- remove doctor command

- add dpy_xor_rectangle for software cursor, remove QECOLOR_XOR
- remove static state for minibuffer handling, use mode specific state attached
to the buffer.

target_window member in EditState.
- remove EditState.minibuf, replaced by WF_MINIBUF flag in EditState.flags
- rename minibuffer commands for consistency
- remove unused global variable debug_flags
- prevent search from minibuffer
- fix toggle-full-screen refresh bug. C-x f is bound to toggle-full-screen
and could be typed by mistake for C-x C-f, switching to full screen mode
but with a refresh delay. This caused confusing behavior interpreted as a
layout bug.
- make charset_ucs2le, charset_ucs2be, charset_ucs4le, charset_ucs4be local
in charset.c
- make edit_detach() and edit_attach() local in qe.c
- redraw status and diag messages in edit_display(). This caused display
bugs in x11 as asynchronous messages were erased by minibuffer window
refresh.

minibuffer is active.
- force put_status message update if message starts with !
- force complete_refresh if window was resized or layout was changed

y yes t true 1 evaluate to true
any other string evaluates to false
the empty string evaluates to def
- add bstr_t type:
constant bounded string with pointer and length.
bstr_make creates a bstr_t from a string pointer or NULL
bstr_token creates a bstr_t from a string upto a separator
bstr_get_nth creates a bstr_t from a the nth element of a string list
bstr_equal compares bstr_t objects for equality
- use macros for type safe registation of command line options
- combine short, long, argument names and help string
- support command line options with optional arguments
- add LF_NOSELECT flag for qe_load_file()
- add find-file-noselect command: load a file into a buffer but do not
attach the buffer to the current window. Due to the current implementation
of set_mode, the buffer is only attached to the file, the file will only be
loaded when it is finally attached to a window.
