As illustrated by the diverse responses you already recevied, the 
question is what you want to achieve.

I recently typeset a Telemann suite with a number of "movements" to be 
played attacca, which in the original print was typeset without any 
separation between these movements. I then took the typesetting decision 
to keep it that way and used a solution more or less identical to your 
example above, with an additional \bar "||" \break between these parts. 
Thanks to the improvements introduced in Lilypond 2.19, these mid-piece 
\partials work smoothly. However, I could also have chosen other ways to 
typeset the music.

If this is a way of saving typing when typesetting music with recurring 
material, you might be able to use \tag to handle slight variations, 
such as shortening a measure that is to be followed by a pickup. Or 
simply leave out the bar that varies, and insert it manually between the 
music that's stored in variables.
