Applied patch by Elmar Loos that adds -m option for mending a box
Changed a few more things to make the box mending patch work in
connection with all the other boxes options
Changes only affect Win32 version. Win32 behavior differs from the UNIX
platforms in the way the config file is searched and the config file
name (boxes.cfg).
Restructured infile/outfile code to eliminate need for access() function
and improve readability
Added file type check before reading config file. boxes used to generate
a weird error message if the config file is a directory
Updated quickinfo (-l -d) with killblank default value
Made indentation computation into a function of its own (get_indent())
Bugfix: REVERSION code may change indentation -> recompute if necessary
Added -k option (kill leading/trailing blank lines on removal yes/no)
Bugfix: REPLACE and indentation conflict. Now applying regexp substitutions
only after indentation was already handled.
smaller data structures. The first design pointed to by designs is always
the one we need (except for ops on *all* designs).
The first design in config file is now default design (no DEF_DESIGN anymore).
Added indent mode command line option for grammar overrides
Moved empty_side() to shape.c after small change in signature
Added text-in-block justification (j) to alignment option (-a)
along with stdarg.h include
Exported input global data and empty_side() function
Declared non-exported functions static
Moved horiz_precalc(), vert_precalc(), horiz_assemble(), vert_assemble(),
horiz_generate(), vert_generate(), generate_box() and output_box() to a
new file generate.c
Moved best_match(), hmm(), detect_horiz(), detect_design(), remove_box()
and output_input() to a new file remove.c
Moved iscorner(), on_side(), isempty(), shapecmp(), both_on_side(),
shape_distance(), empty_side(), highest(), and widest() as well as
some data structures and macros related to shapes to new file shape.c
Moved MAX_TABSTOP, LINE_MAX macros to boxes.h
Moved BMAX, strrstr, btrim(), yyerror(), expand_tabs_into(), regerror(),
empty_line() to a new file tools.c, added #include tools.h
Some cleanup in main()
Declared style_sort() helper function static
Renamed strrstr() to my_strnrstr() (now defined in tools.c)
Default design is now defined by DEF_DESIGN macro
Moved struct opt_t to boxes.h
Bugfix: segfaulted if shape was bigger than input when detecting design
Bugfix: Padding was not removed when box was removed
Bugfix: Forgot null byte when removing west box side
Changed select_design(), because default design value now set in process_commandline()
Move apply_substitutions() regexp handling function up in file
Use apply_substitutions() in read_input() routine also
Moved "extern int yyparse()" prototype to start of file
Added apply_substitutions() routine for central regexp handling
Added regexp reversion code for box removal
Unified use of current_re[pv]rule
Added a few comments and debugging code
Regular expression substituions on input text only if *drawing* a box,
not if the box is to be removed (requires other substitutions, TODO).
Added code for box design auto-detection when removing a box.
