by "ping"ing the PR by adding a comment “Ping”. The common courtesy "ping" rate

The change looks good to me, thanks!
Though the commit line shows [LIB], what is that short for? llvm/lib? library?
Please update it to [TextAPI] instead.

@cyndyishida I don't think @Troy-Butler has commit rights - please can you commit?

@Troy-Butler Congratulations on having your first Pull Request (PR) merged into the LLVM Project!

Your changes will be combined with recent changes from other authors, then tested
by our build bots. If there is a problem with a build, you may receive a report in an email or a comment on this PR.

Please check whether problems have been caused by your change specifically, as
the builds can include changes from many authors. It is not uncommon for your
change to be included in a build that fails due to someone else's changes, or
infrastructure issues.

How to do this, and the rest of the post-merge process, is covered in detail here.

If your change does cause a problem, it may be reverted, or you can revert it yourself.
This is a normal part of LLVM development. You can fix your changes and open a new PR to merge them again.

If you don't get any reports, no action is required from you. Your changes are working as expected, well done!
