shooting in the foot with caret ^ on windows

[anatoly techtonik]

C:\discovery>hg log -r tip^ --style compact

C:\discovery>hg log -r tip^1 --style compact
abort: unknown revision 'tip1'!


The reason for that is that caret ^ is escape character on
windoze. So this command works ok:

C:\discovery>hg log -r tip^^1 --style compact
108   6dab298d9851   2014-05-16 21:40 +0300   techtonik

It would be nice to mention this on

cross-platform alternative.
