While I think the way recent "git commit" displays the commit you just created is very helpful, I often find the double quotes around the message unnecessary and sometimes even confusing. I just made a commit and saw this message:
[master]: created d9a5491: "Show "standard deviation" column in table 3"
The colon after the shortened commit SHA1 is enough to signal that it will talk about a different piece of information on the rest of the line. I think the extra double quotes can be dropped safely:
[master]: created d9a5491: Show "standard deviation" column in table 3
and it will make the output shorter by two columns, more pretty, and does not lose the clarity.
