meyering · Junio C Hamano · commit 67aef034551a · 2006-10-23T14:33:54.000-07:00
This removes trailing blanks from git-generated diff headers the same way a similar patch did that for GNU diff: http://article.gmane.org/gmane.comp.gnu.utils.bugs/13839 That is, it removes trailing blanks on the hunk header line that shows the function name.
