I started two longer runs of these (with otherwise the same settings)
yesterday, printing status after every 50G candidates.  Here's what I am
getting for up to 500G candidates so far.  JtR 1.7.9, the lines
correspond to 50G, 100G, 150G, ... 500G:

The new code (charset.c patch that I posted yesterday), similar 10 lines:

376211g 0:00:51:20 122.1g/s 16233Kp/s 16233Kc/s 5742GC/s icaldjcs..icalt75d

So the advantage on longer runs is smaller (1.2% after 500G here), but
it does exist.

Further lines (up to 900G so far):
