git-annex/Assistant/Gpg.hs
Joey Hess 7b50b3c057 fix some mixed space+tab indentation
This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.

Done as a background task while listening to episode 2 of the Type Theory
podcast.
