Hmm...  The -s added a record to HKLM (the everyone option on setup) and you
had yours located in HKCU (the just me option on setup).

Yes that means binary mode.  However, if you look at the output of cygcheck -s
-r -v carefully you may see two records.  One in HKLM and one in HKCU with
different flag values.  HKCU takes precedence over HKLM.  HKLM keys are used to
allow for multi-user workstations where more than one user uses it.  Any
changes a particular user makes to the mount tables should go to the HKCU. 
This allow HKLM to be the default for a new user.

I wouldn't call it a bug, but it is a misfeature.

If setup had set /cygdrive to binary mode if UNIX files are chosen then you
wouldn't have had this problem and this thread wouldn't exist.  Besides setup
doesn't change what is already existing.  If it does it is a bug.

As for an entry in the FAQ, IIRC there is already discussion of the /cygdrive
pseudo mount.
