Re: [PATCH] config: fix several access(NULL) calls

Matthieu Moy [off-list ref] writes:

When $HOME is unset, home_config_paths fails and returns NULL pointers
for user_config and xdg_config. Valgrind complains with Syscall param
access(pathname) points to unaddressable byte(s).

Don't call blindly access() on these variables, but test them for
NULL-ness before.

This patch causes valgrind warnings in t1300.81 (get --path copes with
unset $HOME) about passing NULL to access():

Indeed. The following patch should fix it.

Thanks!
