Log Message: ----------- vimode: fix line operation problems when NL is missing at EOF
This patch adds \n if it's missing at the EOF before line operations like yank, delete or paste are parformed to make sure these operations always work the same way. If added, the extra \n is removed from the file when the operation is completed.
