RE: [boost] Filesystem Library: Formal Review

If one uses

        string relative_path("libs/locale");
        
that is a relative path is remains a string until converted to a (
absolute ) path.
The conversion to absolute can be relative to any absolute path.

With regard to the UI , the absolute path may be unpleasant but it may
also be the saviour as it explains why the operation failed if the
current directory was not as expected when the relative path was
converted to absolute.

Cannot agree.

     path relative_path("libs/locale");

I intend this path to specify relative path to some other dir, and if 
you convert it to absolute it will be just incorrect.

Even if you make absolute only paths created with system_specific 
decorator...

1. The path non necessary is relative to current dir, it may be relative

to some other implicit directory.

2. Absolute names won't be nice for UI. Consider

     rm a.cpp
     error: cannot remove file /home/ [20 directories] /a.cpp
