- New --keys and --menus options allow to configurate the configuration (!)
file names.

- At startup, after the copyright message a pointer to the F1/ESC keys
is printed.

- Fixed a bad bug related to backward regexp searches.

- New Suspend (SU) command that suspends ne using the TSTP signal

- ARGH! The up_case array does not upper Z!

- replace_regexp wasn't handling correctly the `\\` case

- The up_case array was "downcasing" @ (which of course is nonsense)

- Fixed a small bug in the update of a wordwrapped line

- Fixed a bug in the buffered save code: a line feed (or NUL character) at a
multiple of the length of the save buffer followed by an empty line would
have caused a crash; this was happening currently with line feeds at
multiples of 32768

- Fixed a very stupid bug: the line length field was a short int---sorry

- isspace(), ispuntct() etc. have problems if signed chars are the default
of the compiler. (unsigned char) has been prefixed to the argument of every
call to those functions. Moreover, a call to setlocale() sets correctly the
their behaviour depending on the language chosen by the user.

- Fixed a bug in paragraph(); ne used to try to delete something on a
non-existing line.

- Added information about compilation under SunOS. In particular, an ugly
crashing problem has been tracked to a strange behaviour of realloc(NULL,n),
which returns 0. Moreover, the famous problem with the ESC key (ne was
terminating) has been tracked to bad behaviour of Sun's termcap libraries.

- When creating a file only user read/write permissions were required. Now
all permissions are set up. umask will filter out the unwanted ones.

- Fixed problem when saving preferences files on Linux.

- Fixed problem with macros not being executed automagically.
