+Companion proposal M1e (approved): under Revolution in the window the System
+Menu's save before a launch got -106 on its second CREATE_DIR, and no trace
+had the path. `IPCTRACE RQ` lines now end with ` F <path>` for IOCTLs whose
+input is a 64-byte path (DELETE, GET_ATTR), a 76-byte attribute record (path
+at +6: CREATE_DIR, CREATE_FILE, SET_ATTR) or two paths (` F a > b`, RENAME),
+and for IOCTLVs whose first input vector is 64 bytes (READ_DIR, GET_USAGE);
+` F -` when that field holds no valid path. Read from memory when X1 is
+rung, like the OPEN path; nothing else of the buffers. Checked headless under
+Revolution: `/shared2/test2`, `/title/00000001/00000002/data/cache.dat`, the
+GET_USAGE directories. 95 Starlet tests passed.
