Subject: [PATCH] perf: fix test_export with SHELL=zsh
Message-ID: <8b70d04f-0ad1-6e68-f5a2-2d8ec3bb98ea@web.de>

Unlike other shells, zsh doesn't do word-splitting on variables.  This
is documented in https://zsh.sourceforge.io/FAQ/zshfaq03.html#31.  That
breaks the perf function test_export because it uses a space-separated
variable as a poor man's array, and as a consequence p0000 fails with
"not ok 3 - test_export works".  Pass the value through an unquoted
command substitution to force word-splitting even in zsh.
