#65 wbsh - symlink behaviour

[Peter Wilson]

The Whitebeam Shell (wbsh) currently calls the OS realpath function which examples a relative path into an absolute path within the file system. As part of this process it navigates all symbolic links. The final absolute path therefore contains the targets of symlinks rather than their names.

In cases where symlinks are legitimately used, for example to point to common libraries from within a document root, wbsh can't currently be used. Ideally the path behaviour should match that exhibited by Apache.

This probably means writing out own pathname evaluation/expansion code!
