attr: read core.attributesfile from git_default_core_config
This code calls git_config from a helper function to parse the config entry it is interested in. Calling git_config in this way may cause a problem if the helper function can be called after a previous call to git_config by another function since the second call to git_config may reset some variable to the value in the config file which was previously overridden. The above is not a problem in this case since the function passed to git_config only parses one config entry and the variable it sets is not assigned outside of the parsing function. But a programmer who desires all of the standard config options to be parsed may be tempted to modify git_attr_config() so that it falls back to git_default_config() and then it _would_ be vulnerable to the above described behavior. So, move the call to git_config up into the top-level cmd_* function and move the responsibility for parsing core.attributesfile into the main config file parser. Which is only the logical thing to do ;-) Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
