Subject: prune: Fail gracefully if pre-rm hook fails.
X-Git-Tag: v1.0.1~1^2~7
X-Git-Url: http://git.tuebingen.mpg.de/dss.git/log?p=dss.git;a=commitdiff_plain;h=5874e6d96f97e2dc7bb0771408b298ae5f4e00ed

prune: Fail gracefully if pre-rm hook fails.

In this case wait_for_remove_process() returns non-negative and we
miss to set the exit code, making the command appear to succeed even
if the rm process has not been created.
