solver: handle copies properly

At least enough to get 66 patches applied to handle
/lore/all/34d644a519c/s/?b=target/arm/helper-mve.h
properly.

I noticed this bug due to a:
E: BUG: extra files in index: <100644 e91f526a1a83edb2b56798388a355b1c3729b4bd 0#011target/arm/translate-mve.c>
line in my syslog

However, the $TOTAL in "applying [X/$TOTAL]" in the debug log
is seems off...
