Re: [Linaro-uefi] [edk2] [RFC 1/4] Add "LinuxTerm" terminal type to TerminalDxe

5 Jun 2015

...
This patch adds new terminal type, LinuxTerm, to TerminalDxe.  This terminal
type provides a place to add support for various Linux terminals that don't
behave like standard VT terminals.

I think it best to avoid modifying multiple packages in a single
commit.
For one thing, you should provide a subject prefix, and usually this
should include the package being updated.
https://github.com/tianocore/tianocore.github.io/wiki/Commit-Message-Format
Yet, I think updating all PcAnsi.h files in a separate, single commit
might be okay here. (Although, it seems like only the MdePkg one is
used by this patch, and even that looks like it will need to move
since it is not in the spec. So, maybe no PcAnsi.h files will be
modified now?)
