	  a last-resort fallback (nothing in the environment, etc)
	  (reported by Jakub Wilk <jwilk@debian.org>)
	- allow the default pager value to be overridden at build time
	  (reported by Jakub Wilk <jwilk@debian.org>)

0.1.8	2014/09/11
	- fix a crash when inserting or replacing a half-byte
	  Thanks, Thibaut Girka <thib@sitedethib.com>
	- use CPPFLAGS and LDFLAGS as appropriate during the build
	- create the destination directories during the installation
	- bump the year of my copyright notice on files changed in 2014

0.1.7	2011/07/13
	- fix searching for characters with a code point above 127
	  Reported by: Michael Gold <mgold@ncf.ca> in Debian bug #633508
	- bump the year of my copyright notice on files changed in 2011

0.1.6	2010/12/29
	- fix some errors and warnings detected by cppcheck:
	  - bin2c.c, buffer.c, commands.c, hexer.c - file descriptor leaks
	  - calc.c - a buffer overflow with an overlong command line
	  - main.c - suppress a false positive about a global pointer
	  - regex.c - note that I've been aware of the negative array index
	    problem ever since I first looked at the hexer source code and
	    tried to build it with a raised compiler warning level :)
	- add a TODO list inspired by the cppcheck results
	- bump the year of my copyright notice on files changed in 2010
	- fix a "calcualtor" typo in comments in calc.c and exh.c

0.1.5	2009/09/04
	- taken over by Peter Pentchev <roam@ringlet.net>
	- remove the "bdir" and "ef" settings from the Vim modelines to
	  make them actually acceptable to today's Vim
	- remove most of the settings from the Vim modelines
	- add a config.posix file to reflect a modern POSIX-like system
	- bring config.linux up to date
	- add a HAVE_STRERROR definition to the config files and roll out
	  our own strerror() function if needed
	- clean up the header files:
	  - remove "extern" before the function prototypes
	  - declare all the hexer functions and variables used by
	    other modules
	  - add several header files so that all hexer functions and
	    variables are declared
	  - use ANSI prototypes for all functions
	  - let the prototypes for some functions catch up with reality
	- clean up the source files:
	  - remove the "extern" definitions for the standard C library
	    functions - just include the header files instead
	  - replace the "extern" definitions for hexer functions and
	    variables with the appropriate includes
	  - fix various C compiler warnings
	  - fix some function definitions and calls to match the prototypes
	  - convert all functions to ANSI C prototypes
	  - remove a couple of redundant declarations of functions and vars
	  - rename several variables to avoid collisions
	  - check the result status of various I/O functions
	- clean up the Makefile:
	  - allow the user to override most of the variables
	  - no need to ignore the result of "rm -f" :)
	  - use CFLAGS when building bin2c
	  - do not try to follow dependencies for termlib.c
	  - simplify the "install" target and honor DESTDIR if set
	- rename the KEY_* constants to HXKEY_* to avoid conflicts with
	  the curses header files
	- add an "hx_" prefix to the "lines", "columns", and
	  "insert_character" variables for the same reason
	- garbage-collect some unused functions
	- fix the manual page syntax:
	  - fix the comment markers
	  - mark the hyphens as such where needed
	- remove some hyphenation in the help text
	- switch the Makefile to use curses by default
	- link with the math library for pow(3) used in the calculator
	- rename the TERMCAP and TERMLIB Makefile variables to LTERMCAP
	  and LTERMLIB; the TERMCAP environment variable is actually
	  defined in some environments, and it is definitely not
	  a linker library specification!
	- fix a case of undefined behavior in tio.c: the v*printf()
	  routines may NOT be called a second time with the same
	  varargs list!  Add a HAVE_VASPRINTF definition and enable it
	  on Linux systems; it is also available on modern BSD's, but
	  the config.bsd file needs a lot of updating anyway.
	  Reported by: Michael Gold <mgold@ncf.ca> in Debian bug #540571
	- add a HAVE_MEMMOVE definition to the config files; buffer.c and
	  regex.c already test for it

0.1.4c
	- the last version released by Sascha Demetrio <demetrio@cs.uni-sb.de>
