--color-diff='.' considered useful

git tip of the day:

git diff --color-words='.'
git show --color-words='.'

That will help you find that 1 character change that a failed default
word split hides from your eyes.

I guess everyone here will know already, but I found that super useful
and much easier than trying to get a meaningful word split for that 100+
char TeX source line without a single space...

Cheers,
Michael
