| GIT v1.6.4.1 Release Notes | 
 | ========================== | 
 |  | 
 | Fixes since v1.6.4 | 
 | ------------------ | 
 |  | 
 |  * An unquoted value in the configuration file, when it contains more than | 
 |    one whitespaces in a row, got them replaced with a single space. | 
 |  | 
 |  * "git am" used to accept a single piece of e-mail per file (not a mbox) | 
 |    as its input, but multiple input format support in v1.6.4 broke it. | 
 |    Apparently many people have been depending on this feature. | 
 |  | 
 |  * The short help text for "git filter-branch" command was a single long | 
 |    line, wrapped by terminals, and was hard to read. | 
 |  | 
 |  * The "recursive" strategy of "git merge" segfaulted when a merge has | 
 |    more than one merge-bases, and merging of these merge-bases involves | 
 |    a rename/rename or a rename/add conflict. | 
 |  | 
 |  * "git pull --rebase" did not use the right fork point when the | 
 |    repository has already fetched from the upstream that rewinds the | 
 |    branch it is based on in an earlier fetch. | 
 |  | 
 |  * Explain the concept of fast-forward more fully in "git push" | 
 |    documentation, and hint to refer to it from an error message when the | 
 |    command refuses an update to protect the user. | 
 |  | 
 |  * The default value for pack.deltacachesize, used by "git repack", is now | 
 |    256M, instead of unbounded.  Otherwise a repack of a moderately sized | 
 |    repository would needlessly eat into swap. | 
 |  | 
 |  * Document how "git repack" (hence "git gc") interacts with a repository | 
 |    that borrows its objects from other repositories (e.g. ones created by | 
 |    "git clone -s"). | 
 |  | 
 |  * "git show" on an annotated tag lacked a delimiting blank line between | 
 |    the tag itself and the contents of the object it tags. | 
 |  | 
 |  * "git verify-pack -v" erroneously reported number of objects with too | 
 |    deep delta depths as "chain length 0" objects. | 
 |  | 
 |  * Long names of authors and committers outside US-ASCII were sometimes | 
 |    incorrectly shown in "gitweb". | 
 |  | 
 | Other minor documentation updates are included. |
