Issue in Supercite, or in mu4e?

[Alexis]

Hi all,

i've been setting up Supercite to use with mu4e, and found that 
the "initials" attribution preference wasn't working; it would 
only provide the author's first initial. Digging into 
`supercite.el`, i found that the issue stems from 
`sc-attribs-extract-namestring`:

   (sc-attribs-extract-namestring "Joan Smith")    ; "Joan"
   (sc-attribs-extract-namestring "Joan Smith <>") ; "Joan Smith"

When `sc-attribs-extract-namestring` is passed a string which 
doesn't contain '<' and '>' to delimit an email address, it only 
extracts the first name, which then results in only one initial 
being extracted.

i can probably find some way of working around this, but what i'm 
wondering is: should this be considered an issue with Supercite 
(or how i've set it up), or an issue with mu4e (or how i've set it 
up)?
