Subject: [PATCH] W45: Marked-file total size in panel footer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Append a 'Σ <size>' indicator to the panel footer when files
are marked, using the info colour. Sums the stat.size of every
entry whose name is in the marked set (directories included).
Helps users see the combined size before bulk operations like
copy/move/delete.

Tests: 1405 pass, zero warnings.
