[PATCH v2 1/9] add-interactive: make sure to release `rev.prune_data`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

During a review, Junio Hamano pointed out that the `rev.prune_data` was
copied from another pathspec but never cleaned up.
