Subject: war on whitespaces: documentation.
X-Git-Tag: v1.3.0-rc1~94
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=8273c79ae2e6b782dba3dccb815b386cc83e4294;p=git.git

war on whitespaces: documentation.

We were missing the --whitespace option in the usage string for
git-apply and git-am, so this commit adds them.

 	result.  This allows binary files to be patched in a

+--whitespace=<option>::
+	When applying a patch, detect a new or modified line
+	that ends with trailing whitespaces (this includes a
+	line that solely consists of whitespaces).  By default,
+	the command outputs warning messages and applies the
+	patch.
+	When `git-apply` is used for statistics and not applying a
+	patch, it defaults to `nowarn`.
+	You can use different `<option>` to control this
+	behaviour:
++
+* `nowarn` turns off the trailing whitespace warning.
+* `warn` outputs warnings for a few such errors, but applies the
+  patch (default).
+* `error` outputs warnings for a few such errors, and refuses
+  to apply the patch.
+* `error-all` is similar to `error` but shows all errors.
+* `strip` outputs warnings for a few such errors, strips out the
+  trailing whitespaces and applies the patch.

+	When no `--whitespace` flag is given from the command
