Sure, but not as visibly as documented above. For example under sh
$: cd c:/HoME/PiErRe
$: /bin/pwd

I has a look at the code and it is the Windows path that is adjusted,
not the Posix path. I think it was always like that.
In the case of chdir, the change in the Posix path was a result of former
transformations of the Windows path back to Posix form. Those can cause
trouble when several Posix paths point to the same Windows path (the mapping
Posix -- Windows is not bijective). In particular the final text/binary mode
need not be as expected, and this caused complaints.
