vertical alignment - how to bottom-align something?

[Janek Warchoł]

Hi,

i have something like this:

\markup {
    \line {
        \someMarkup
        "foobar"
      }
  }

(someMarkup can be a markup of any height)
I want "foobar" to be automatically bottom-aligned.

For example let's have
someMarkup = \markup {
    \column {
        "bla" "bla" "bla" "bla" "bla" "bla" "bla"
      }
  }

I'd like to have "foobar" vertically aligned with the last "bla", no
matter how many "bla"s are there.

How can this be done?

I *cannot* use this approach:

\markup {
    \column {
        "bla" "bla" "bla" "bla" "bla" "bla"
        \line { "bla" "foobar" }
      }
  }
