Multiple special characters in a single <...> does not work as documented

[phreed]

In the documentation https://github.com/antlr/stringtemplate4/blob/master/doc/cheatsheet.md is the following:

<\ >, <\n>, <\t> | special character(s): space, newline, tab. Can have multiple in single <...> expression, e.g. <\t\t>. -- | --

I tried to use '<\n\t' and ST4 produced the error: expecting '>', found '\' Replacement with '<\n><\t>' works as expected.

That's weird. Thanks for letting me know.
