Conventionally (Guile) Scheme symbols are lowercase and don't use dots.
I suppose you could do 'user-signing-key'.

However, there seems to be quite some duplication between 'user',
'author' and 'committer'.  Perhaps you could abstract things a little
by e.g. doing something like the git-user-info record I proposed?

(home-git-configuration
  (user (git-user-info (name ...) (e-mail ...) (signing-key ...))
  (author user)
  (committer user)
  [other options])  

Greetings,
Maxime.
