Now you are wiser, because you know that it happened 940 revisions before v0.99.
Unset::
- Unsetting the `crlf` attribute on a path is meant to
- mark the path as a "binary" file. The path never goes
- through line endings conversion upon checkin/checkout.
+ Unsetting the `crlf` attribute on a path tells git not to
+ attempt any end-of-line conversion upon checkin or checkout.
Unspecified::
commit hash.
+USING ATTRIBUTE MACROS
+----------------------
+
+You do not want any end-of-line conversions applied to, nor textual diffs
+produced for, any binary file you track. You would need to specify e.g.
+
+------------
+*.jpg -crlf -diff
+------------
+
+but that may become cumbersome, when you have many attributes. Using
+attribute macros, you can specify groups of attributes set or unset at
+the same time. The system knows a built-in attribute macro, `binary`:
+
+------------
+*.jpg binary
+------------
+
+which is equivalent to the above. Note that the attribute macros can only
+be "Set" (see the above example that sets "binary" macro as if it were an
+ordinary attribute --- setting it in turn unsets "crlf" and "diff").
+
+
+DEFINING ATTRIBUTE MACROS
+-------------------------
+
+Custom attribute macros can be defined only in the `.gitattributes` file
+at the toplevel (i.e. not in any subdirectory). The built-in attribute
+macro "binary" is equivalent to:
+
+------------
+[attr]binary -diff -crlf
+------------
