Subject: filter-branch: assume HEAD if no revision supplied
X-Git-Tag: v1.5.4~6
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=0f047f3b47693e8f80a00bcf4af421d9d2fc7efd;p=git.git

filter-branch: assume HEAD if no revision supplied

filter-branch previously took the first non-option argument as the name for
a new branch. Since dfd05e38, it now takes a revision or a revision range
and modifies the current branch. Update to operate on HEAD by default to
conform with standard git interface practice.
