You may think so (as I thought so too before hitting a snag or two) ;-).

The thing is, failing "wget --output-document" leaves an empty file,
and an empty file does not still cause "if type jgit; then" to take
the "else" clause, and the invocation of "jgit version" would fail,
taking the whole thing out, due to the "set -e" thing.
