[issue7315] os.path.normpath doesn't normalize ../path/something.py

James <purpleidea at gmail.com> added the comment:

i looked at the source for normpath.
i know that it doesn't look at the filesystem.
assuming you're not currently sitting at the root directory, in all? 
cases ../xyz brings you back to where you started. we expect normpath to 
clean up a path string, collapsing '../' (as documented), perhaps either 
the docs should state otherwise, or this should collapse dirs as long as 
they are present in the path given to it ?

as an aside is there any reason why normpath shouldn't look at the 
filesystem and decide if it makes sense to collapse a leading '../' when 
this case arises ?
