[PATCH] D116174: [clang] support relative roots to vfs overlays

[Ben Langmuir via Phabricator via cfe-commits]

benlangmuir added a comment.

Each VFS may have its own working directory, so it could be surprising if we use the OS working directory instead of that.  This is complicated by the fact the VFS working directory may not be set yet during parsing the yaml (I haven't checked).  I'm not really sure what to recommend here. If we do change this, we should document the new behaviour in the doc comment for RedirectingFileSystem though.
