C-a hhardcopy [-h] [file]
Writes out the currently displayed image to the file file, or, if no
filename is specified, to hardcopy.n in the hardcopydir directory,
where n is the number of the current window. This either appends or
overwrites the file if it exists (according to hardcopy_append).
If the option -h is specified, also dumps the contents of the
scrollback buffer.
