Open Radar

 
Summary:
All of sudden, Xcode has stopped rendering more than 3 tabs in a row in the text editor. If you have the file, it actually saves all of the tab presses you made but it won't display them. If you open a file containing lines with more than 3 tabs at the beginning, they will all be rendered as if there were 3 tabs.

Steps to Reproduce:
Repro 1:
1) Open a new source file (C is fine)
2) Press the tab key more than 3 times in a row on a single line
3) Notice that the cursor stops moving after the 3rd tab press

Repro 2:
1) Open a file containing containing lines starting with more than 3 tabs
2) Notice that the line is rendered as if there were only 3 tabs

Expected Results:
All of the tabs in the file would be rendered

Actual Results:
Only the first 3 tabs are rendered

Regression:
I never saw this in any previous version of Xcode

Notes:
* I tried disabling automatically trim trailing whitespace and it didn't make a difference
* Attached are 2 screenshots of a file with a lot of indenting. One screenshot shows how Xcode is rendering the file, the other shows how TextEdit renders the file. I also included the source file that I used when taking those screenshots.

I've been able to track this down to using the Inconsolata-dz font (http://nodnod.net/2009/feb/12/adding-straight-single-and-double-quotes-inconsola/). If I modify a theme to use Inconsolata-dz and then restart Xcode, I start seeing this tab issue. If I use Menlo or another font, Xcode renders tab correctly.
