X-Git-Tag: v2.9.3~26^2~3
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/508a285ceab4523412546a92cd9444f8e78065e1?hp=--cc

submodule-config: use explicit empty string instead of strbuf in config_from()

Use a string constant instead of an empty strbuf to shorten the code
and make it easier to read.
