Subject: [PATCH] W50: Editor MarkAll, InsertFile, BlockSave, Close commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MC parity gap: the editor F9 menu was missing 4 commands that
MC has. This adds them all:

- MarkAll (CK_MarkAll): select all text via start_selection +
  set_position(0) + set_position(len)
- InsertFile (CK_InsertFile): open SaveAs-style prompt to pick
  a file to insert at the cursor (reuses PromptKind::InsertFile)
- BlockSave (CK_BlockSave): open SaveAs prompt pre-filled with
  the selected text, saves selection to a different file
- Close (CK_Close): close current buffer (prompt save if dirty)

All 4 added to the F9 File and Edit menus. Test updated for
new file menu item count (7→11).

Tests: 1407 pass, zero warnings.
