spacing

[Palmer, Ralph]

Greetings -

I'm running LilyPond V 2.11.27 under Win XP SP2.

I've been typesetting scales and arpeggios, and I noticed that the
spacing of the eighth note triplets is not constant in the following.
It's not huge, but the triplets in the first half of the first measure
clearly have a wider spacing than the rest. Is this a bug, or did I
inadvertently alter something? Also, when I ran <convert-ly> on my
scales (which were previously in LP 2.11.23), the \version "2.11.23" did
not update to "2.11.27". Is that expected? Do I need to update each
individual file? The command I ran was : convert-ly -e *.ly

Thanks for your time and help,

Ralph
