- Create a grid with dashes even in -%/--usage mode. This was surprisingly annoying since it breaks the existing 1 block = 1 char assumption. - Derive percentages from in-use blocks, not all blocks. This matches behavior of tracebd.py's percentages (% read/prog/erase). Though not tracebd.py's percent wear... - Added mdir/btree/data counts/percentages to dbgbmapd3.py, for use in custom --title strings and the newly added --title-usage. Because why not. Unlike dbgbmap.py, performance is not a concern at all, and the consistency between these two scripts helps maintainability. Case in point: also fixed a typo from copying the block_count inference between scripts.
