Hi.
  I finally had time to debug my problems with pre_process and ttree
in more detail.

It turned out that ttree thinks PRE_PROCESS and POST_PROCESS are
multiple value fields, so it returns the values supplied for them as arrays,
eg

  pre_process = foo:bar

is sent to Template as PRE_PROCESS => [ 'foo:bar' ]. The delimiter splitting
routines in Template::Service only split up if values are scalars rather
than array references, so it wasn't getting split, and therefore it tried
to pre_process the file 'foo:bar'.

ttree learnt that those two fields were arrays sometime between beta5 and
rc2, I'm not sure why.

One fix, as far as I can tell, is to apply this patch:

Which reverts this change. However, if this was originally done for a good
reason, it's not the end of the story. The modified version passes all tests
still, but I can't see that they actually exercise ttree.
