Subject: Fix trace in case of space evaluation
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=8f30d233f891efc561ba3446ef8b9560c8369645;hp=ec83e8a72c702713d550fb2a228f56a6c03704c4

Fix trace in case of space evaluation

We only compute space eval during the opening/early midgame.
Apply the same logic for DoTrace.

No functional change.
