Andrea Bolognani c0ac533b6f qapi: Stop using whitespace for alignment in comments 
Perfectly aligned things look pretty, but keeping them that
way as the schema evolves requires churn, and in some cases
newly-added lines are not aligned properly.

Overall, trying to align things is just not worth the trouble.

#
# - base64: the data read is returned in base64 encoding.
