description:
Contrib: vim syntax adjusted to save cpoptions (ticket #2276).

Line continuation as used in the syntax file might be broken if "compatible"
is set or "C" is added to cpoptions.  Fix is to set the "cpoptions" option
to vim default value at script start and restore it later, see
":help use-cpo-save".
