Subject: base-files: functions.sh: prepend() always adds separator
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=95157dde046058f745437a37a35d8136c8c84608;p=openwrt%2Fstaging%2Fnbd.git

base-files: functions.sh: prepend() always adds separator

It shouldn't gate on the value, since the value will ostensibly
always be set; instead it should depend on the variable being
prepended to being non-empty.

Fixes #14403
