Amichai Rothman commented on ZOOKEEPER-1663:
--------------------------------------------
The array was used in order for that glob expression to expand properly into
multiple paths where each can contain a space (e.g. if ZOOKEEPER_PREFIX
contains a space), so they can be passed on as such - as opposed to a single
string with spaces in it (losing the individual paths) or multiple strings with
no space in them (cutting the individual paths in the middle where they contain
spaces), which is what the simpler syntax achieves. Both alternatives would
fail when passed as arguments to a command later on. An array is the only way I
found to do this, but if there is a better way, by all means use it.
