bug#21679: [PATCH] 25.0.50; Use pretty symbols from Lisp mode in Scheme mode

["Simen Heggestøyl" <simenheg@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1101 bytes --]

Lisp mode has a `prettify-symbols-alist' for prettifying lambda as λ.
Let's give Scheme mode pretty lambdas too, by borrowing Lisp mode's
`prettify-symbols-alist'.
