Revision 283884422f35594db9eab491d3f8c91e49f9d62f authored by Junio C Hamano on 29 July 2007, 00:20:52 UTC, committed by Junio C Hamano on 30 July 2007, 06:28:55 UTC
Earlier these tools refused to create a reflog entry when the message given by the calling Porcelain had a LF in it, partially to keep the file format integrity of reflog file, which is one-entry-per-line. These tools should not be dictating such a policy. Instead, let the codepath to write out the reflog entry worry about the format integrity and allow messages with LF in them.
