converted to LF upon checkin, but there is no conversion done
upon checkout.
+If `core.safecrlf` is set to "true" or "warn", git verifies if
+the conversion is reversible for the current setting of
+`core.autocrlf`. For "true", git rejects irreversible
+conversions; for "warn", git only prints a warning but accepts
+an irreversible conversion. The safety triggers to prevent such
+a conversion done to the files in the work tree, but there are a
+few exceptions. Even though...
+
+- "git add" itself does not touch the files in the work tree, the
+ next checkout would, so the safety triggers;
+
+- "git apply" to update a text file with a patch does touch the files
+ in the work tree, but the operation is about text files and CRLF
+ conversion is about fixing the line ending inconsistencies, so the
+ safety does not trigger;
+
+- "git diff" itself does not touch the files in the work tree, it is
+ often run to inspect the changes you intend to next "git add". To
+ catch potential problems early, safety triggers.

`ident`

attribute set to `jcdiff`, it calls the command you specified
with the above configuration, i.e. `j-c-diff`, with 7
parameters, just like `GIT_EXTERNAL_DIFF` program is called.

+Built-in merge drivers
+^^^^^^^^^^^^^^^^^^^^^^
+
+There are a few built-in low-level merge drivers defined that
+can be asked for via the `merge` attribute.
+
+text::
+
+ Usual 3-way file level merge for text files. Conflicted
+ regions are marked with conflict markers `<<<<<<<`,
+ `=======` and `>>>>>>>`. The version from your branch
+ appears before the `=======` marker, and the version
+ from the merged branch appears after the `=======`
+ marker.
+
+binary::
+
+ Keep the version from your branch in the work tree, but
+ leave the path in the conflicted state for the user to
+ sort out.
+
+union::
+
+ Run 3-way file level merge for text files, but take
+ lines from both versions, instead of leaving conflict
+ markers. This tends to leave the added lines in the
+ resulting file in random order and the user should
+ verify the result. Do not use this if you do not
+ understand the implications.
+

Defining a custom merge driver
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-The definition of a merge driver is done in `gitconfig` not
-`gitattributes` file, so strictly speaking this manual page is a
-wrong place to talk about it. However...
+The definition of a merge driver is done in the `.git/config`
+file, not in the `gitattributes` file, so strictly speaking this
+manual page is a wrong place to talk about it. However...
To define a custom merge driver `filfre`, add a section to your
`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
internal merge and the final merge.
+Checking whitespace errors
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`whitespace`
+^^^^^^^^^^^^
+
+The `core.whitespace` configuration variable allows you to define what
+`diff` and `apply` should consider whitespace errors for all paths in
+the project (See linkgit:git-config[1]). This attribute gives you finer
+control per path.
+
+Set::
+
+ Notice all types of potential whitespace errors known to git.
+
+Unset::
+
+ Do not notice anything as error.
+
+Unspecified::
+
+ Use the value of `core.whitespace` configuration variable to
+ decide what to notice as error.
+
+String::
+
+ Specify a comma separate list of common whitespace problems to
+ notice in the same format as `core.whitespace` configuration
+ variable.

EXAMPLE
-------
If the attribute `export-subst` is set for a file then git will expand
several placeholders when adding this file to an archive. The
expansion depends on the availability of a commit ID, i.e. if
-gitlink:git-archive[1] has been given a tree instead of a commit or a
+linkgit:git-archive[1] has been given a tree instead of a commit or a
tag then no replacement will be done. The placeholders are the same
-as those for the option `--pretty=format:` of gitlink:git-log[1],
+as those for the option `--pretty=format:` of linkgit:git-log[1],
except that they need to be wrapped like this: `$Format:PLACEHOLDERS$`
in the file. E.g. the string `$Format:%H$` will be replaced by the
commit hash.
