If possible, please do not use sub-processes like in your suggested
patch. How about
variants="$variants
$(list_tool_variants)"
It leaves a blank line at the beginning of $variants instead of the end
and should not make a difference in the outcome of
variants="$(echo "$variants" | sort | uniq)"
BTW, is `sort -u` not available everywhere?
