They always were meant to be case-insensitive, but I had missed one "tolower()", making that not true.

The actual _values_ aren't case-insensitive, of course, although some uses of them may be (ie boolean parsing uses "strcasecmp()" to match against the strings "true" and "false").

This should independent of the other patch - it should apply whether you've taken the [user]name/email config thing or not. But it was generated on top of that change.
