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.
