Since commit b7efb43e86 (download/git: try to recover from
utterly-broken repositories), we catch errors through an ERR
trap, so we can try and recover from a broken repository. In
that commit, we switched from using "set -e" to "set -E", so
that trap is inherited in functions, command substitutions,
and subshells.
However, the trap is not defined until we have parsed the
options, created the cache directory, and eventually chdir()ed
into it. Athough improbable, it is possible for the git helper
to fail in any of those steps, and that would not get caught.
Fix that
