A blob's plaintext length is already in every frame kind -- a zlib container states it outright, a delta carries it in its own header -- so --size reports one without resolving a chain. The binary verdict cannot be had that way (a NUL may be the last byte), so --long still reads every blob and keeps its exact columns.

The larger cost was neither: resolveHexPrefix scanned the whole store per file to resolve a full-width name the digest index answers outright, which slowed plain ls too. On tcl's tip --long drops 167s to 93s and --size costs what plain ls costs. check-in: 3b7e8c7569 user: dmestas tags: trunk
