If a batch file is run without CRLF line endings (ie LF-only) then arbitrary behavior may occur. I consider that a bug in Windows, however the effects can be serious enough (eg unintended code executed) that we're fixing it in the repo by requiring CRLF line endings for batch files on checkout. Prior to this change the checked-out line endings of batch files were dependent on a user's git preferences. On Windows it is common for git users to have automatic CRLF conversion enabled (core.autocrlf true), but those users that don't would run into this behavior. For example a user has reported running the Visual Studio project generator batch file (projects/generate.bat) and it looped forever. Output showed that the Windows OS interpreter was occasionally jumping to arbitrary points in the batch file and executing commands. This resulted in unintended files being removed (a removal sequence called) and looping forever.
