Changes in version 1.15:

Files are now saved by lines (not by bytes), which is about one order of
magnitude faster.

'Auto unmark' now turns off highlighting by reducing block size to 0 instead
of resetting the block. This way the beginning of the block can still be
reached with Alt-B.

Move window to the first column after word wrapping at right margin.

One more space has been inserted between columns in the help screens showing
the 'Character Set'.

The chapter 'Syntax of command-line arguments' has been added to the manual.
