[PATCH v2 4/4] git-p4: failure because of RCS keywords should show help

["Ben Keene via GitGitGadget" <gitgitgadget@gmail.com>]

From: Ben Keene <seraphire@gmail.com>

When applying a commit fails because of RCS keywords, Git
will fail the P4 submit. It would help the user if Git suggested that
the user set git-p4.attemptRCSCleanup to true.

Change the applyCommit() method that when applying a commit fails
becasue of the P4 RCS Keywords, the user should consider setting
git-p4.attemptRCSCleanup to true.
