Mark customizable variables (user options) in the summary line

User options are variables declared with defcustom. It is useful to
know if a variable is a user option or not, because if it isn't, it's
usually not safe to set it in the init file.

Calling user options "customizable variables" makes it clear that a
user option is still a variable. This is kind of like how interactive
functions are not referred to as "commands" in the summary.
