If I remember correctly (and what I checked to be true), while '=' cannot
be part of keyname nor section name, it can be part of subsection name,
therefore it can be part of fuly qualified key name.

The '\n' can _not_ be part of subsection name, therefore it can not be
part of fully qualified key name.

  $ cat > conftest <<EOF
  [section "sub=section"]
       truekey=true
       emptykey=
       novalkey
  EOF

  $ GIT_CONFIG=conftest git-config -l
  section.sub=section.truekey=true
  section.sub=section.emptykey=
  section.sub=section.novalkey
