Subject: [PATCH] Fix "HGPLAIN" environmental variable in Windows

Summary: In Windows, you can't use `X=y cmd` syntax to set variables. Use "set X=y & cmd" instead.

Test Plan:
  - Ran "arc diff" in a Mercurial repo in Windows, created D2367.
  - Verified this does //not// cause 'HGPLAIN' to be set in the outer shell (where you type "arc diff").
