I think I was the one claiming that.  Don't believe it -- it's not
true :-)  I mixed up the global and buffer-local value of
`gnus-summary-line-format-spec'.

*But* byte-compiling the format-spec seems to have a very insignificant
influence on performance.  I can't measure any difference in the total
time, and timing the difference between 

  (with-temp-buffer
    (dotimes (i 100000)
      (eval gnus-summary-line-format-spec)))

with and without byte-compiling suggests that the difference for the
total time should be less than 1% ... at least for my summary-line.
