Thanks for importing my Kconfig lexer, but because the patch was old there was an update that went unnoticed. I just committed it and kindly request you to pull it upstream. It should simplify Trac integration, but uses reflection (import inspect), so please review it before pulling. I hope it is acceptable.
Sounds reasonable from a Pygments perspective. The thing is, I guess Trac does tab expansion either for all files or for none, and I guess it does so before sending them to Pygments. So indentation-aware support would only work for Kconfig if it would also be applicable to tab-expanded files with a variable tab width (we use 4 at Freetz). I.e. Pygments would not see any tabs and it would not be safe to asssume that a tab always equals 8 spaces. This is what makes my lexer so complicated and why I added this hack in the first place.
Should you ever add indentation-aware support in the way Kconfig files sent by Trac need it, please do not hesitate to ask me to be a tester. I am no longer with Freetz, but this ugly little lexer is my baby, so I will test it for you.
P.S.: Maybe you can accept the comment updates unrelated to Trac, i.e. everything in this patch except "import inspect" and the "special case" hunk? It is just cosmetics, but anyway.
