From 1.8.2 lib:

$ grep " do " `find . -name "*.rb"` | wc -l
    1104
$ grep " do " `find . -name "*.rb"` | grep "end" | wc -l
      37 
$ grep "{ *|" `find . -name "*.rb"` | wc -l
    1047
$ grep "{ *|" `find . -name "*.rb"` | grep "}" | wc -l
     647

I know, it's not 100% reliable... but it suggests that, at least
roughly, 3% of 'do' blocks end on the same line, while 62% of {}
blocks end on the same line.  So this "odd" behavior is actually
pretty canonical :-)
