To elaborate (I briefly talked to Sarajärvi on IRC): this isn't about
the fatal error; we downgraded this to a nonfatal error in 4698c8f
(config: allow inaccessible configuration under $HOME, 2013-04-12).
Rather, it's very strange that 'git config --file foo' tries to look at
any config file other than 'foo'. In a git repo:
$ strace git config --file fooconfig test.var 2>&1 | grep 'open.*config'
open("/home/thomas/.gitconfig", O_RDONLY) = 3
open(".git/config", O_RDONLY) = 3
open("/home/thomas/.gitconfig", O_RDONLY) = 3
open(".git/config", O_RDONLY) = 3
open("fooconfig", O_RDONLY) = 3
I haven't looked into the code yet. Probably it's simply following the
usual code paths to discover a repo and read its config. However, with
the --file option, it shouldn't.
