Add a missing check to makedefs so it prints a warning about misplaced %Es.
Fix a couple places in quest.txt pointed out by the new warning.
There's no visible effect on play, since the code that actually reads the
message keeps reading until the next %C.
From one of <Someone>'s ascension posts: the introductory message

the time. This rewording acknowledges the difference between being
blind or sighted, but it is still a bit odd to able to know which flag
is flying when unable to actually see it.
