Motion by Characters
--------------------

   These functions move point based on a count of characters.
`goto-char' is the fundamental primitive; the other functions use that.

 - Command: goto-char position
     This function sets point in the current buffer to the value
     POSITION.  If POSITION is less than 1, it moves point to the
     beginning of the buffer.  If POSITION is greater than the length
     of the buffer, it moves point to the end.

     If narrowing is in effect, POSITION still counts from the
     beginning of the buffer, but point cannot go outside the accessible
     portion.  If POSITION is out of range, `goto-char' moves point to
     the beginning or the end of the accessible portion.

     When this function is called interactively, POSITION is the
     numeric prefix argument, if provided; otherwise it is read from the
     minibuffer.

     `goto-char' returns POSITION.

 - Command: forward-char &optional count
     This function moves point COUNT characters forward, towards the
     end of the buffer (or backward, towards the beginning of the
     buffer, if COUNT is negative).  If the function attempts to move
     point past the beginning or end of the buffer (or the limits of
     the accessible portion, when narrowing is in effect), an error is
     signaled with error code `beginning-of-buffer' or `end-of-buffer'.

     In an interactive call, COUNT is the numeric prefix argument.

 - Command: backward-char &optional count
     This function moves point COUNT characters backward, towards the
     beginning of the buffer (or forward, towards the end of the
     buffer, if COUNT is negative).  If the function attempts to move
     point past the beginning or end of the buffer (or the limits of
     the accessible portion, when narrowing is in effect), an error is
     signaled with error code `beginning-of-buffer' or `end-of-buffer'.

     In an interactive call, COUNT is the numeric prefix argument.
