> Note that we would '''not''' log the output of command `A` in a `make`
rule like
{{{
#!make
target: prereq
A && pipestatus "B" "tee -a logfile"
}}}
In fact also not with my version of `pipestatus`, where one would instead
use
{{{
#!make
target: prereq
pipestatus "(A && B)" "tee -a logfile"
}}}
(If `A` is e.g. `cd spkg` there, we would also - as we currently do - use
`tee -a ../logfile` there, because `A && B` is '''explicitly''' executed
in a subshell.)
