For Windows users using cmd.exe:

Character ^ is interpreted as an escape character by cmd.exe. So, if you want
to get ^ through to hg you have to use something like

> hg log -r.^^

which counts as a single ^ or

> hg log -r."^"

If you ignore that, you will get a funny "More?":

> hg log -r.^
More?

I will add a note about that to the ParentrevspecExtension wiki page.
