Refactor t0024 to avoid having multiple chaining commands on a single
line, according to current styling norms.

e.g turn
    ( mkdir testdir && cd testdir && echo "in testdir" )
into:
    mkdir testdir &&
    (
        cd testdir &&
        echo "in testdir"
    )

This is also described in the Documentation/CodingGuidelines file.

Sure.  

	Subject: t0024: style fix

	t0024 has multiple command invocations on a single line,
	which goes against the style given by CodingGuidelines.

would be sufficient.

I think we assume "$TAR" is modern enough to know about the "C"
option (see t/t5004-archive-corner-cases.sh), so

	mkdir untarred &&
	"$TAR" Cxf untarred test.tar

without even a subshell may be sufficient.

I do not think we assume "$GIT_UNZIP" to always know about the
equivalent of "C" (is that "-d exdir"?), so what you wrote is the
best we can do.

Thanks.

Will update it in v2.

Yeah, "-d exdir" would be the equivalent, but there's no mention of it
in the testcases in t5003 or t5004. So, keeping it as is in v2.

Thanks.

I suppose '"$TAR" Cxf untarred test.tar' is not a valid syntax on
alpine, since it was breaking CI.

Instead changed it to '"$TAR" xf test.tar -C untarred' in v3, which
is how it's written in t/t5004-archive-corner-cases.sh, which passes
CI.
