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.

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.

Return statement is not a function so remove superfluous use of parenthesis.

This functions is only used internally by basic.c, so marking it static,
to make it private.

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.

Lets welcome uEmacs/PK to the year 2010! As expected, the patch has no effect
on the generated code:
text data bss dec hex filename
106002 8864 18616 133482 2096a em
106002 8864 18616 133482 2096a em.new

This is a slightly updated version of uemacs-PK (PK is Pekka
Kutvonen) which was used at Helsinki University a long time
ago. My fingers cannot be retrained.
