Revision 1855c044629a02488baa1bd25ae45341da33bd4e authored by Junio C Hamano on 09 July 2005, 02:27:15 UTC, committed by Linus Torvalds on 09 July 2005, 02:48:44 UTC
If it is fed a commit with more than one leading blank lines, the sed scripts git-format-patch-script used looped forever. Using git-stripspace upfront makes the sed script somewhat simpler to work around this problem. Also use git-rev-parse so that we can say $ git-format-patch-script HEAD^^^^ to prepare the latest four patches for e-mail submission.
