This update fixes a few issues in history editing and the processing
of the "quit" function. The "quit" function will no longer cause bc
to exit when encountered in a script file (before any command from
the script has been executed).
New functions is_number(), is_string return 1 if the passed argument
is a number resp. a string. The asciify() function has been extended
to support the conversion of an array of numbers into a string.

This version adds support for command line editing and history using
the libedit or readline libraries in addition to the line editing
features available in previous versions.
The version in the base system is configured to use libedit.
This allows to choose between emacs and vi line editing commands and
to use command overrides via a ~/.editrc file.

This version adds options and functions that allow to print numbers
in the open interval (-1 .. 1) with or without a leading 0 digit.
Additionally, an option has been added to prevent line wrap and
allows to print arbitrarily long results on a single line.

This is a new major release with a number of changes and extensions:

- Added the ability to assign strings to variables and array elements
and pass them to functions in bc.
