Batch files should use CRLF endings. LF endings mostly work but in some situations they cause random errors like goto commands failing for mysterious reasons. See golang.org/issue/37791 for more information. Next CL triggered one of such bug (a label was not being recognized), so prepare for it by converting to CRLF. This CL also touches all existing batch files to force git to update the line endings (unfortunately, changing .gitattributes only has effect next time the file is checked out or modified). Fixes #37791 Updates #9281 Change-Id: I6f9a114351cb7ac9881914400aa210c930eb8cc1 Reviewed-on: https://go-review.googlesource.com/c/go/+/96495 Run-TryBot: Giovanni Bajo <rasky@develer.com> Reviewed-by: Ian Lance Taylor <iant@golang.org> Reviewed-by: Alex Brainman <alex.brainman@gmail.com>
