Linus Torvalds ddd45dbff1 Fix 'getccol()' and 'getgoal()' functions for multibyte UTF-8 characters 
These functions convert the byte offset into the column number
(getccol()) and vice versa (getgoal()).

Getting this right means that moving up and down the text gets us the
right columns, rather than moving randomly left and right when you move
up and down.  We also won't end up in the middle of a utf-8 character,
because we're not just moving into some random byte offset, we're moving
into a proper column.

Linus Torvalds 6b793211c2 Make cursor movement (largely) understand UTF-8 character boundaries 
Ok, so it may do odd things if it's not truly utf-8, and when moving up
and down lines that have utf-8 the cursor moves oddly (because the byte
offset within the line stays constant, rather than the character
offset), but with this you can actually open the UTF8 example file and
move around it, and at least some of the movement makes sense.

Thiago Farina 7622263b45 uemacs: Make getgoal function private to basic.c. 
This functions is only used internally by basic.c, so marking it static,
to make it private.

Thiago Farina 834bfd37aa uemacs: basic.c: Add support to go to the end of the buffer. 
There is a case when the user can type something like this:

    em filename +

or even

    em +

Instead of saying "Bogus argument" when the uemacs start, just go to the end of
the buffer like we can do in vim for example.
