[support] Drush changes permissions and overwrites htaccess

[Tim Johnson]

Drush is 
  changing permissions on the target root (@stage)
    755 to 750
  and 
    overwritting .htaccess (@stage)
  When I run 
    drush rsync @dev @stage
How can I prevent these two actions?

As ever, I'm sure there is a documentation or discussion on these
matters. I'm not clear from example.aliases.drushrc.php

thanks
