In Version 1.13.0 the behavior of "^^" in ALIASES is not properly evaluated:

In my project I've an alias like

ALIASES = "INCEXAMPLE{1} = <div style=\"margin-left:50px;\"> ^^ \par \1 ^^ \snippet{doc} example.md \1 ^^ </div>"

which includes an example from another file with indentation.

This produces several warnings:

• warning: Found unknown command '@ilinebr'
• warning: end of comment block while expecting command (Probable start 'C:/Daten/Doxygen/Issues/Test24_ilinebrk/mainpage.md' at line 4)

and (of course) weird output.

Seems that Doxygen treats all the text after the filename "example.md" as blockmarker instead only upto "^^".
see attached zip-file

This behavior is not restricted to snippet command but also appears in other commands I used in several aliases like:

• ALIASES = "CONDSECTION{1} = \if condition ^^ \section \1 \1 ^^ \endif"
• ALIASES = "INCSNIPPET{3} = \dontinclude{lineno} \1 \skipline \2 ^^ \until \3"

Additionally in doxywizard displaying those aliases are wrongly formatted - s. Screenshot in zip-file.
This only behaves on "Show configuration", the doxyfile itself is written correctly,
and also behaves to all older versions (tested back upto Doxygen version 1.8!
--> Maybe this should be an extra issue?
