Subject: js: Do not unconditionally set gen_update_hook
X-Git-Tag: otter-0.5.0~294
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=9d9ed8b8ba870b20f28f0d8103d96ee922f8900a;p=otter.git

js: Do not unconditionally set gen_update_hook

When we reload, can bust the tests, as the hook gets overwritten.
I think.
