git tricks!?

I think the github has as bug: it lost the file history when the file is renamed. Basically, it is unable to track the file location across the time... maybe because a bad commit/push ratio, maybe because the 'git mv' was not used... I tried make some staged updates and, although it does not worked for git hub, it appears to had worked for cmd line, for example the darlibc/io.c is a very old file and the history is fully tracked:

$ git config --global log.follow true
$ $ git log io.c | grep Date

unfortunately, the github does not show this history... very sad :(

In this case you can use double dashes: "git log -- filename"
(include the full path to the removed/renamed file)
