The Indentation Nightmare

If there is something that I have never fully understood during the last years of learning programming languages, it's the chaos around indentation. Some says that you should use spaces, some others says that you should use tabs. And even if you're willing to use spaces, there will be multiple schools, some people saying that you should use two spaces, instead of four for some other developers.

Why is it such a mess ? I don't even see why it is such a debatable topic : indentation is made by tabs. Alignment is made by spaces. Nothing more, nothing less. Want to know why ?

Spaces have a fixed length

Spaces are usefull because they have a fixed length. It means that it should be used when you have to align code. What's aligning ? Take this piece of code :

Beautiful scripts

(based on "Beautiful Days", by Venus :)

I wish I had let
Weak maps and spread
I wish I had const
And minimal classes

I wish I had rest
Pragma and tails

Git Pivotal

git pivotal --start <branch_01234567>|<01234567>
  Creates a new branch, sets its upstream to the correct remote branch then
  sets the task state to 'started'. If the branch name is omitted, the script
  will use the name of the current branch. If the branch name only contain an
  issue ID, the script will try to make use of the _git_pivotal completion.

git pivotal --clean
