Merge branch 'jk/config-use-size-t'

The config API made mixed uses of int and size_t types to represent length of various pieces of text it parsed, which has been updated to use the correct type (i.e. size_t) throughout. * jk/config-use-size-t: config: reject parsing of files over INT_MAX config: use size_t to store parsed variable baselen git_config_parse_key(): return baselen as size_t config: drop useless length variable in write_pair() parse_config_key(): return subsection len as size_t remote: drop auto-strlen behavior of make_branch() and make_rewrite()
