instead of several; and do some other minor refactoring of
related display functions to simplify them. New functions
mark_order() and display_string(); changes to actual_x(),
edit_add(), update_line(), statusbar(), and
do_replace_highlight(). (David Benbennick) DLR: Add minor
cosmetic tweaks, add missing NANO_SMALL #ifdef around the text
for a backwards search in the refactored code, and enclose
dump_buffer() and dump_buffer_reverse() in one ENABLE_DEBUG
#ifdef instead of two.

- Convert memmove() function calls to charmove() macro calls, as
the former all work on char*'s. (DLR)
