Subject: [PATCH] Revert "Don't anchor the regexp to EOL to fix matching issues
 that were causing the entire block of crontab entries to appear twice in the
 crontab. This could be due to the way cron is adding newlines or some other
 post-processing that occurs on the cron. This bug was reproduced in the
 following environment: Ubuntu 10.04.2 LTS, rvm 1.0.14, ruby 1.8.7 patchlevel
 253, capistrano 2.5.19, capistrano-ext 1.2.1, bundler 1.0.10"

This reverts commit 1f11510d8735bb4201730c7f71b580a4b04a6ba8.
