some bash versions require EOL cont for bracketed calls

No idea why, but recently my new system started complaining about a shell syntax error. I guess this went unnoticed before because of some leniency in the bash parser. Either way, this PR fixes the syntax error.

LGTM! (looks like a leftover, other parts in bootstrapper are covered)

Yes indeed...

Any idea which bash version? Anyway, this LGTM as well.

I was actually wrong - we use /bin/sh in the bootstrapper, and on my system that points to dash with version 0.5.12.
