nano syntax highlighting: GNU makefiles

May I present, another highlighting syntax for the nano editor... This time for GNU makefiles.

Code & Instructions:

# GNU makefile highlighting

syntax "mk" "(\.mk|(^|/)(GNU)?[Mm]akefile)$"

# default text
color magenta "^.*$"
# rules: command

To install, save the above above code snippet as a file called mk.nanorc in the folder /usr/share/nano/ (or /usr/local/share/nano/ or similar if you feel strongly about the /usr <--> /usr/local separation), and then add the following to the end of the file /etc/nanorc:

## GNU makefiles
include "/usr/share/nano/mk.nanorc"

Nano will then use it to highlight all files that are called makefile / Makefile / GNUmakefile, or have the .mk filename suffix.
To use it for highlighting a makefile with a different filename, you can manually activate it using nano's -Y command line switch, like so:

nano -Y mk path/to/myMakefile

Here's a screenshot of this highlighting definition used on a demo file that includes various makefile-snippets to show off different syntax features:
