On windows, under cygwin.

I just saw

    $ hg histedit -r .~2
    warning: tags associated with the given changeset will be lost after

    do you want to continue (yN)?  n
    abort: histedit cancelled

The 'n' just appeared, I did not input it. I'm guessing it's an 
interaction with cygwin's mintty.

I started up a windows "CommandPrompt" and the command stopped for 
input, I entered 'y' and was able to continue.

Looks like '-f' is taken for something else (I didn't try it). Maybe '-q 
y' as an option? But I have a viable workaround, and it doesn't happen 
often. The tag came from a git push.
