This is a fix for a new bug in the v2.30 cycle:

`git maintenance [start|stop]` add and/or remove entries to/from the
user's cron table. When inserting entries, we add magic "BEGIN" and
"END" markers. When we later removes these entries, we remove everything
from "BEGIN" to ... the end of file. A realistic scenario for hitting
this bug is

  $ git maintenance start
  $ crontab -e # add stuff at the end of the file
  $ git maintenance stop
  $ crontab -l # stuff from above is gone

The second patch is the actual fix. The first patch is just a very minor
fix to the documentation. The third patch future-proofs the magic
markers, so that we can be reasonably sure that all future versions of
Git stick to these strings.
