[gollem] problem with "change directory" and file backend

[Liam Hoekenga]

Ok... so the problem seems to be that if use "change directory" with a 
relative path, it tries to change to

vfsroot / path

instead of

vfsroot / current directory / path

I got around that by adding this to the CHANGE_DIRECTORY block in 
manager.php ...

but if I do that, that breaks the tilde expansion that we submitted as 
a patch last night (and we'd very much like to see tilde expansion 
become part of Gollem and / or the VFS file backend).

At my last attempt at doing tilde expansion, Chuck had suggested that 
we implement that in VFS instead of Gollem itself (to avoid building 
dependancies for a specific VFS backend into gollem itself).

I guess my question is... what should horde/lib/VFS/file.php's 
_getNativePath be passed?  Should it be able to handle relative paths, 
or only absolute?  Because w/o any of our changes, it only do absolute 
paths.  Should we make sure that any path we send it has been turned 
into an absolute path before it gets there?  If so, where's the logical 
place to put the tilde expansion stuff w/o building a "file" backend 
dependency into Gollem (as ~username is a specialize relative path)?
