2022-07-17Fix bug where 'program-arities' returns #<unspecified> (issue #23)VCGS40Y
program-arities now returns an empty list if no arities information is found. This fixes the bug that happens when calling, say, `(autodoc '(display))`, which leads to following error: ``` scheme@(guile-user)> (autodoc '(display)) ice-9/boot-9.scm:1669:16: In procedure raise-exception: In procedure map: Wrong type argument: #<unspecified> Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue. scheme@(guile-user) [1]> ,q ```
