doc/reference_manual.texi:
Give a reason why nonabstract instance declarations may not appear
in interface sections. To make this reason understandable, delay it
until we have discussed method definitions.
Add an example of an abstract instance declaration with a typeclass
constraint.
compiler/split_parse_tree_src.m:
Improve the wording along lines suggested by Julien.
tests/invalid_nodepend/instance_bug.err_exp:
Expect the updated wording.
