+Subject: [PATCH] dpkg-deb: increase buf lengh in movecontrolfiles
+
+In some cases limit of 200 is too short.
+For example, on gentoo we build in /var/tmp/portage (user configurable)
+
+the buf contents end up exactly 201 characters:
+e.g.: "mv /long/path /another/long/path && rmdir /yet/another/long/path"
+
+so we only catch it in testsuite and dpkg-deb tests fail sometimes.
