note vs discussion comment difference

[prarit]

I noticed this while working on the commit comment code but felt it was slightly out of scope for that changeset.

When you start a comment with 'mr note' lab adds, for example:

# This comment is being applied to OPEN Merge Request 1166 commit ee6d5ceeadc8f6d8e71a565bb50fcff5e98992fa.
# Do not delete patch tracking lines that begin with '|'.
# Write a message for this note. Commented lines are discarded.

And when you start a discussion with 'mr discussion' lab adds, for example:

# Write a message for this note. Commented lines are discarded.

These really should be the same. I'll work on a changeset today to synchronize the messaging.
