Subject: [PATCH] don't allow cursor to wrap at BOL in cursor_beyond_eol mode

enabling "Cursor beyond end of line" ("virtual whitespace") mode stops
right-arrow from wrapping into the next line. however, left-arrow
continued to wrap to the previous line. this asymmetry felt highly
unnatural and often caused "navigation challenges" for me.

consequently, this patch makes left-arrow stop at the beginning of the
line in virtual whitespace mode. put differently, it couples BOL
wrapping to EOL wrapping. just about every other editor that has such a
switch behaves this way (FAR's being the only other exception known to
me).
