When -U0 is used, trim_common_tail should be called after `xdl_diff`, so
that `--indent-heuristic` (and other diff processing) works as expected.
It also removes the check for `!(xecfg->flags & XDL_EMIT_FUNCCONTEXT)`
added in e0876bca4, which does not appear to be necessary anymore after
moving the trimming down.
This only adds a test to t4061-diff-indent.sh, but should also have one for
normal (i.e. non-experimental) diff mode probably?!

The changed test script passes just fine for me even without your change
to xdiff-interface.c, which is odd. Do you have another way to
demonstrate the unexpected behavior? And can someone replicate the
failure?
