When trying to make a move to github from bitbucket I've encountered fatal error in one of commits:
error in commit d8b1774aa7bd98c6494a1e31acef943d0e0cbf03: missingSpaceBeforeDate: invalid author/committer line - missing space before date
cat-file shows:
author john <john@doe.com>removed backup files. Modified <> 1397201439 +0200
committer john <john@doe.com> 1397201439 +0200
How can I amend this commit and add missing space?
