Recent upgrade to wish leads to a problem

OK, thanks. I'm really miserable about this advance which has messed 
badly with my preferred MO (amongst other things, not using X). I tried 
to revert but got into a tangle (and in fact ended up with no wish* 
under /bin, at all). I have recovered a non-updated Cygwin from about a 
month ago (i.e. wish -> wish84.exe) which of course offers many 
opportunities for updating packages using setup.exe.

It is not clear to me which update opportunity I should decline in order 
to keep wish -> wish84.exe and not move to wish -> wish8.5.exe. 
Searching for this executable under Search packages yielded

Search Results
Found 1 matches for wish8.5.exe
tcl-tk/tcl-tk-8.5.11-1    Tcl X11 toolkit

so I de-selected this. However, watching the update process unfold, it 
is clear that *something else* uninstalled tcl-tk (I saw the phrase 
"Uninstalling tcl-tk"). Was it expect? python? both of which were 
selected in the update process. So as before, I have ended up with no 
wish* under /bin, at all. (Possibly some dependency is missing in 
setup.ini? Also there appears to be nothing under [prev] under tcl-tk :o( )

I will try to recover the working version from 1 month ago and start again.

Q1 It would be good to know what recent update, separate from tcl-tk 
explicitly listed above, has led to the un-installation of the existing 
tcl-tk. Any ideas?

Q2 In some other contexts Cygwin provides "nox" versions additionally to 
versions requiring a running X server. Is there any chance that 
tcl-tk-8.4 could be recovered and offered as a nox version?

Thank you.
Fergus
