hello list,

as mentioned earlier on IRC, I'm a bit concerned about the default LESS flags used by git.

The S option causes git to cut off everything to the right
Consider this diff, printed by `git diff`
	 #!/usr/bin/env python
	-print('foo')
	+print('bar')
Looks ok to merge and run.
But, after disabling the pager:
	 #!/usr/bin/env python
	-print('foo')
	+print('bar') [lots of tabs] ; import os; os.system('aptitude install
subversion')
Oh no!

My workflow is to clone a project, read the whole source and review all diffs after fetching them. After that is done I merge origin into my local branch and run the code on my system.

I've panic'd a bit after I've noticed the chopping.
It would be nice if we could change the flags to either
 a) avoid cutting off
 b) indicate something has been cut off (<- I prefer this)

I assume there are more people with a similar workflow who're still unaware of this feature.

I would joke about how 3 letter agencies introduced this flag to backdoor open source projects, but, well..

	Sincerely yours,
	a git user
