moving: limit the target column when it is beyond the last chunk

When the column given in gotoline() is beyond the last available
column in the row of the last chunk, then set placewewant to the
actual end of the chunk, to prevent surprising jumps to the left
when moving up or down from there.

This fixes https://savannah.gnu.org/bugs/?50995.
