Well, in a team with a bunch of programmers each with their own preferences is kind of tedious to talk and enforce a single formatting standard...
So, I just make sure a small script runs
#astyle -A2SKnjfUHpk1cn -R .h .cpp
before their commits .. and it made my diff look much nicer.. I don't really discuss tabs or spaces anymore..
I never thought that such styling would really matter much ... I wonder how much a developer using a beautifier earns in average..
Anyhow, statistics sometimes brings up some weird conclusions.
