Subject: [PATCH] Fix bug #28898 lldb: libedit produces garbled, unusable input
on Linux
Apply patch from Christos Zoulas, upstream libedit developer.
It has been tested on NetBSD/amd64.
New code supports combination of wide libedit and disabled
LLDB_EDITLINE_USE_WCHAR, which was the popular case on Linux
systems.
