Re: [RFC] Provide a mechanism to turn off symlink resolution in ceiling paths

This is a possible implementation (untested!) of Junio's suggestion,
with the slight twist that the empty entry can appear anywhere in
GIT_CEILING_DIRECTORIES and only turns off symlink expansion for
subsequent entries.

Sounds like a good way to go, I think.

Originally I thought that checking with the elements literally and
stop when we have a match, and then falling back to call realpath()
on them to compare, might be a solution, but I do not think it is.
I haven't thought things through to convince myself that is the best
approach to require the users to explicitly tell us to omit calls to
realpath().  Perhaps it is the best we could do, but there might be
even better ways somebody can think up.
