New Revision: 251457
URL: http://llvm.org/viewvc/llvm-project?rev=251457&view=rev
Log:
Fix editline unindentation code for more recent libedits.
This code was modifying the cursor and then expecting the editline
API call to see the effect for the next operation. This is misusing
the API. Newer editlines break on this code, fixed by this.
