Subject: transport-helper.c: refactor set_helper_option()
X-Git-Tag: v2.11.0-rc0~68^2~25
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/9318c5dd140b55c0384843c57b4b24a378cd5068

transport-helper.c: refactor set_helper_option()

For now we can handle two types, string and boolean, in
set_helper_option(). Later on we'll add string_list support, which does
not fit well. The new function strbuf_set_helper_option() can be reused
for a separate function that handles string-list.
