This reversion is necessary in all cases, and I think we should get rid of
it so it's not necessary, since the default beatLength will produce this
beaming.
Once you have reverted the undesired auto-beam setting, you have three ways
to set the desired auto-beam setting:
1) use #(override-auto-beam-setting '(end * * 2 4) 2 4)
2) use \set beatGrouping = #'(2)
or
3) adjust the beatLength.

My preference is to use beatGrouping, because it's the most intuitive to me.
Here's a snippet that shows all three methods in use.
\version "2.12"
\score {
\relative c' {
\time 2/4
c'8 d e f
#(revert-auto-beam-setting '(end * * 2 4) 1 4)
#(override-auto-beam-setting '(end * * 2 4) 2 4)
c8 d e f
#(revert-auto-beam-setting '(end * * 2 4) 2 4)
\set beatLength = #(ly:make-moment 1 2)
c8 d e f
\set beatLength = #(ly:make-moment 1 4)
\set beatGrouping = #'(2)
c8 d e f
}
}
Thanks,
Carl
