According to 'man 3 printf', without the '.' you have a field width
that specify the minimum size of the field (and you get the full
commit id, no truncation).

With the '.' it becomes a precision option and becomes the maximum
number of characters of the field (and the commit id gets truncated to
7 chars).

printf() can even pick the length of the field from a parameter
(instead of harcoded in the format string) with  '%.*s'.
