Subject: [PATCH] ./Makefile: consider PAGER for `make help'
Date: Tue, 29 Sep 2020 22:05:01 +0200 [thread overview]
Message-ID: <gh3630mk2o.fsf@gouders.net> (raw)
`make help' outputs more than a screenfull of lines.
In case a user has PAGER defined in his environment, she most likely
wants it to be used in such situations.
