xml2rfc should not change the case of the initials when derived from fullname

[kesara]

Description

At the moment, xml2rfc always use the uppercase for initials when initials are derived from the fullname attribute.¹

But when initials and surname is provided, xml2rfc doesn't change the case.

Examples:

<author fullname="jane Doe"></author>

generates: J. Doe

<author fullname="jane doe"></author>

generates: J. doe

<author fullname="jane doe" initials="j" surname="doe"></author>

generates: j. doe

In the case of single letter names, both

<author fullname="j doe" surname="doe"></author>

and

<author fullname="j doe"></author>

generates: J doe

Note that kramdown-rfc has its own set of heuristics to convert a "name:" attribute (not an xml2rfc attribute) into initials/surname.
(See handle_name in lib/kramdown-rfc/refxml.rb for details.)
Maybe not directly relevant, but at the end I'd like to document how those heuristics work together.
