records: Let thunked fields refer to their inherited value.
* guix/records.scm (make-syntactic-constructor)[field-index]: New procedure.
[wrap-field-value]: Add optional argument ‘parent’. When it is true, bind F
to the inherited field value.
[field-bindings/inheritance]: New procedure.
Use it.
* tests/records.scm ("define-record-type* & thunked & no inherited value")
("define-record-type* & thunked & inherited value")
("define-record-type* & thunked & inherited value & this-record"): New tests.
* doc/guix.texi (Defining Package Variants): Update ‘modify-inputs’ example to
refer to ‘inputs’.
(Writing Manifests): Likewise.
* doc/guix-cookbook.texi (Package Variants): Likewise for
‘substitute-keyword-arguments’.
