As Peff said, responding in a thread started by Linus's suggestion
to raise the default abbreviation to 12 hexdigits:
This is waayy too large for a new default. The vast majority of
repositories is smallish. For those, the long sequences of hex digits
are an uglification that is almost unbearable.
I know that kernel developers are important, but their importance has
long been outnumbered by the anonymous and silent masses of users.
Personally, I use 8 digits just because it is a "rounder" number than 7,
but in all of my repositories 7 would still work just as well.
