I had the same reaction upon reading the patch. It's not just other
scripts in which the problem might manifest, but a change to the value
of some variable which is used as a command invocation. Providing a
"fix" for this one particular case may help get past test a failure on
Alpine under busybox, but it is not a good general solution. (Some
sort of helper function which smooths away differences like this --
say git_indirect_cmd() or something -- which can be used wherever a
$VARIABLE is invoked as a command might be a better approach, but I
haven't really thought it through.)
