progress: make determinate bar more like wget progress bar

foo [                                                          ]  0/58
foo [>                                                         ]  1/58
foo [=>                                                        ]  2/58
...
foo [=======================================================>  ] 56/58
foo [========================================================> ] 57/58
foo [=========================================================>] 58/58

The bar now has a '>' character at the end. This indicates the direction,
is consistent with the indeterminate '<=>' bar, and looks much nicer.
