Explicit <head> arguments to git-prune replaces, instead of extends, the list of heads used for reachability analysis by fsck-objects. By giving a subset of heads by mistake, objects reachable only from other heads can be removed, resulting in a corrupted repository. This commit stops replacing the list of heads, and makes the command line arguments to add to them instead for safety. Signed-off-by: Junio C Hamano <junkio@cox.net>

git-prune - Prunes all unreachable objects from the object database
|

SYNOPSIS
|
|
--------
|
|
'git-prune' [-n] [--] [<head>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
This runs `git-fsck-objects --unreachable` using all the refs
|
|
available in `$GIT_DIR/refs`, optionally with additional set of
|
|
objects specified on the command line, and prunes all
|
|
objects unreachable from any of these head objects from the object database.
|
|
In addition, it
|
|
prunes the unpacked objects that are also found in packs by
|
|
running `git prune-packed`.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-n::
|
|
Do not remove anything; just report what it would
|
|
remove.
|
|
|
|
--::
|
|
Do not interpret any more arguments as options.
|
|
|
|
<head>...::

|
|

|
|
reachable from listed <head>s.

EXAMPLE
|
|
-------
|
|
|
|
To prune objects not used by your repository nor another that
|
|
borrows from your repository via its
|
|
`.git/objects/info/alternates`:
|
|
|
|
------------
|
|
$ git prune $(cd ../another && $(git-rev-parse --all))
