message-citation-line-format - should %F have a fall back?

[asjo@koldfront.dk (Adam Sjøgren)]

Should %F in message-citation-line-format fall back to something
different than nil, if no first name can be detected?

Like, say, the email address?

,----[ C-h v message-citation-line-format RET ]
| message-citation-line-format is a variable defined in `message.el'.
| Its value is "%F writes:
| "
| Original value was 
| "On %a, %b %d %Y, %N wrote:\n"
| 
| Documentation:
| Format of the "Whomever writes:" line.
| 
| The string is formatted using `format-spec'.  The following constructs
| are replaced:
| 
|   %f   The full From, e.g. "John Doe <john.doe@example.invalid>".
|   %n   The mail address, e.g. "john.doe@example.invalid".
|   %N   The real name if present, e.g.: "John Doe", else fall
|        back to the mail address.
|   %F   The first name if present, e.g.: "John".
|   %L   The last name if present, e.g.: "Doe".
|   %Z, %z   The time zone in the numeric form, e.g.:"+0000".
| 
| All other format specifiers are passed to `format-time-string'
| which is called using the date from the article your replying to, but
| the date in the formatted string will be expressed in the author's
| time zone as much as possible.
| Extracting the first (%F) and last name (%L) is done heuristically,
| so you should always check it yourself.
| 
| Please also read the note in the documentation of
| `message-citation-line-function'.
`----

Or is there already some way of doing this? The "you should always check
it yourself" might be implying so?

It is kind of weird to get "nil writes:" when From: is just an email
address...

What do y'all think?
