+Quotes in file names *win32-quotes*
+
+Quotes inside a file name (or any other command line argument) can be escaped
+with a backslash. E.g. >
+ vim -c "echo 'foo\"bar'"
+
+Alternatively use three quotes to get one: >
+ vim -c "echo 'foo"""bar'"
+
+The quotation rules are:
+
+1. A `"` starts quotation.
+2. Another `"` or `""` ends quotation. If the quotation ends with `""`, a `"`
+ is produced at the end of the quoted string.
+
+Examples, with [] around an argument:
+ "foo" -> [foo]
+ "foo"" -> [foo"]
+ "foo"bar -> [foobar]
+ "foo" bar -> [foo], [bar]
+ "foo""bar -> [foo"bar]
+ "foo"" bar -> [foo"], [bar]
+ "foo"""bar" -> [foo"bar]
