Pagedown: travis fails to deploy to gh pages

[RLesur]

@yihui I've noticed that the two latest travis builds have failed to deploy to gh-pages:

• travis build #393 is OK
• there is a fatal error bad config line 1 in file /home/travis/.gitconfig with
  travis build #394 and travis build #395

The git configuration file https://xran.yihui.name/.gitconfig seems to be correct. I don't understand what is the problem.

fixed by https://github.com/rstudio/pagedown/commit/0907291c8f3389671645757f29ca88d3e2beda5a and https://github.com/rstudio/pagedown/commit/8fa63601a29fc131ebacf5dd1e0e212d744d8654

I haven't noticed that your personal domain has changed.

In .travis.yml, I should have used curl -L so that curl can follow the redirect. Thank you!
