"Bind each custom variable FORM to the value of its VAL. "Bind each custom variable FORM to the value of its VAL.
FORMS is a list of pairs of values [FORM VAL]. FORMS is a list of pairs of values [FORM VAL].
`customize-set-variable' is called sequentially on each pairs
contained in FORMS. This means `csetq' has a similar behaviour as
`setq': each VAL expression are evaluated sequentially, i.e. the
first VAL is evaluated before the second, and so on. This means
the value of the first FORM can be used to set the second FORM.
If FORM has a custom setter, use it to set FORM to VAL. The return value of `csetq' is the value of the last VAL.
Otherwise, use `set-default'.
