Comment(by leif):
P.S.:
While with my approach one can force the behavoir Jeroen expects (by using
parentheses), the opposite is impossible. On the other hand, one ''could''
of course also do something like
{{{
#!sh
$ A && pipestatus "B" "C"
}}}
to get the behavior of
{{{
#!sh
$ A && B | C # same as pipestatus "A && B" "C" with my version
}}}
with Jeroen's version, but that's IMHO odd, at least in Makefiles where we
mainly use it (and `A` there would potentially be executed by a
''different'' shell than the parameters to `pipestatus`, `B` and `C`).
The name of the script (and the current "syntax description") suggests not
to use other things than simple commands for each of the two parameters
anyway I think.
