[bug#55845] [PATCH 1/1] ui: Improve pager selection logic when less is not installed.

[Taiju HIGASHI]

This is off-topic.

I feel I have a limited vocabulary available to me in Guile or Scheme
(as well as in English...) , but functions like pk were not included in
Guile's reference or Scheme's reference, so I thought my chances of
knowing them were quite limited. (I didn't know about in-vicinity
either, but now that I know it is in SRFI.)

Are these the kind of things you learn by reading the source?
