SOURCE BUG Duration: 8s

Subject

Ok, I've converted the contents of the "testing/sed" directory into a sed.tests file. My brain hurts now. (Lots of boggling at sed minutiae and corner cases and going "why is gnu giving that output". The behavior of N and n with regard to EOF are only understandable if you read the Open Group spe

SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): scripts/config/mkconfigs.c (2005-08-01 - 2006-10-05 arasi) uretilen bbconfigopts.h icine .config satirlarini kacissiz, ham newline'larla gömüyordu - gecerli C degildi, busybox'un kendi bb_mkdep araci bile parse edemiyordu (7d219aab7 ile duzeltildi, mkconfigs shell scripte cevrildi)

→ Bu hatanin tam hikayesini ve duzeltme diffini gor
