I meant --show-prefix.  ad36c84 (worktree setup: calculate prefix even
if no worktree is found, 2010-04-05) teaches rev-parse to produce a
nonempty prefix even when there is no workdir but didn’t update the
documentation:

    --show-prefix
         When the command is invoked from a subdirectory, show the
         path of the current directory relative to the top-level
         directory.

I suspect it’s a good change.  Git ought to correctly honor relative
paths on the command line even when there is no work tree.  But the
semantics are not clear any more --- when there is no top-level
directory, what is the prefix relative to?

Probably my other words of warning were also too extreme.  I have been
using a copy of git with nd/setup included, and aside from the
ls-remote problem I mentioned, I haven’t run into any trouble.
