In current 5.0 branch, --autocomplete shows results in `-foo -bar` format, but changed this to show ``` -foo [foo's helptext] -bar [bar's helptext] ``` which is a quite large change in --autocomplete API. So I hope this to be merged in 5.0, to avoid a large API difference between 5.0 and 6.0. Fixed in commmit: https://reviews.llvm.org/rL309113
Merged to 5.0 in r309437 (llvm part) and r309438 (clang part).
