 notes:
-    - When running fetch with C(become), the M(slurp) module will also be
-      used to fetch the contents of the file for determining the remote
-      checksum. This effectively doubles the transfer size, and
-      depending on the file size can consume all available memory on the
-      remote or local hosts causing a C(MemoryError). Due to this it is
-      advisable to run this module without C(become) whenever possible.
-    - Prior to Ansible-2.5 this module would not fail if reading the remote
-      file was impossible unless fail_on_missing was set.  In Ansible-2.5+,
-      playbook authors are encouraged to use fail_when or ignore_errors to
-      get this ability.  They may also explicitly set fail_on_missing to False
-      to get the non-failing behaviour.
-    - This module is also supported for Windows targets.
