The message line wrapped badly on 80 column wide ttys. Use a shorter
hint text to make the message fit on an 80 column wide terminal
without wrapping.
Add a blank line before the hint so the hint is more easily noticed
from the suggested commit message when a Change-Id is missing.
Make the curl command a single line with ; in between the two
commands, making copy and paste into a shell easier.
Don't use $ before a command name, instead start the command with
two spaces so it offsets from the left margin slightly more than
other text.
Change appends from "\n" to '\n'. Its only a single character.
