The commit message only needs to mention the type you actually
changed, in this case `gnus-article-treat-head-custom'

`t' is a const, not a boolean, the same as `nil', in the context of
defcustom. Plus a lot of the docstrings look cut&paste, so Iʼm not
entirely sure that itʼs the existing type that is wrong rather than
the docstring.
