in the "fctx" mode with the "annotate" command, the client also downloads the

the fastannotate cache (built server-side, downloaded client-side) in two repos
|
|
|
have the same content (because the client downloads from the server)
|

$ diff $p1/a.l $p2/a.l

$ diff $p1/a.m $p2/a.m

in the "fctx" mode, the client could also build the cache locally
