[PATCH] git-am: Add colon before the subject that is printed out as being applied

git-am output can be confusing, because the subject of the applied
patch can look like the rest of a sentence starting with "Applying".
The added colon should make this clearer.

Hi,

Linus added single quotes to applypatch in 610968199,
writing:

    Add quotes around the subject line that we print out as being applied.

    My brain just flipped when it tried to read the "Applying" as part
    of the explanation of the patch, and the sentence didn't make any
    sense. The quotes make it clear what's going on.

I think he is right ;)

Of course, it's debatable whether
	Applying: foo
or
	Applying "foo"
or
	Applying 'foo'
may be the best. I don't really care :)

The main reason I chose the colon variant is because the change in t4151
is less ugly.

Another reason: thinking of "ambiguous" subjects:
 -	Applying "Remove "string" from foo.c"
 -	Applying 'Remove 'string' from foo.sh'
 -	Applying: foo.c: Remove "string"

Regards,
  Stephan
