Subject: bash prompt: don't use '+=' operator in show upstream code path
X-Git-Tag: v1.8.4.3~11^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52ec889d1ab3405796dd4fb4c262f950927a6b71;p=thirdparty%2Fgit.git

bash prompt: don't use '+=' operator in show upstream code path

The '+=' operator is not supported by old Bash versions (3.0) we still
care about.
