Another fs command I can't find any documentation for:  fs precache

In this case, it appears that there's no way to query the value.   This
seems like bad interface design to me.  If there's a mechanism for setting
an important value that changes the behavior of the client, there has to be
a mechanism for querying that value.  Otherwise, you can't manage it.
 Write-only, read-never parameters are very bad.

Looking at the code in src/venus/fs.c, it looks to me like this *should*
have been implemented as a pair of CLI commands: setprecache and
getprecache, and in fact, that should be straight forward, and fully
backwards compatible.

Is this another bleeding edge feature that the authors thought wasn't
important enough to write a man page for?
