Hmm, i'd say that \once \override could work like tweak.  Currently
\once \override affects all objects created at the same moment in
given context, but i think it wouldn't be of much inconvenience if it
affected only a single object, like tweak does.

The reason i'm so concerned about it is because today i managed to do
unbelieveable amount of mistakes when trying to move a markup.  I've
forgotten about the hash, the quote and the dash (in different
combinations) before i finally wrote -\tweak #'X-offset #3 .  At some
moment i even thought it cannot be done like that.
A shame - only i'm not sure who should be ashamed more, me or Lily :P
