> FileSystem#globStatus and FileContext#globStatus need to work with symlinks.  Currently,
they resolve all links, so that if you have:
> {code}
> /alpha/beta
> /alphaLink -> alpha
> {code}
> and you take {{globStatus(/alphaLink/*)}}, you will get {{/alpha/beta}}, rather than
the expected {{/alphaLink/beta}}.
> We even resolve terminal symlinks, which would prevent listing a symlink in FSShell,
for example.  Instead, we should build up the path incrementally.  This will allow the shell
to behave as expected, and also allow custom globbers to "see" the correct paths for symlinks.
