Merge branch 'jk/maint-config-alias-fix'

* jk/maint-config-alias-fix:
handle_options(): do not miscount how many arguments were used
config: always parse GIT_CONFIG_PARAMETERS during git_config
git_config: don't peek at global config_parameters
config: make environment parsing routines static

Conflicts:
config.c
