Merge branch 'jk/maint-config-param'
* jk/maint-config-param: config: use strbuf_split_str instead of a temporary strbuf strbuf: allow strbuf_split to work on non-strbufs config: avoid segfault when parsing command-line config config: die on error in command-line config fix "git -c" parsing of values with equals signs strbuf_split: add a max parameter
