With something like (see editors/ghostwriter for an example port)
portlint -AC wrongly complains
WARN: Makefile: extra item placed in the USES/USE_x section, for example, "GH_ACCOUNT".
0 fatal errors and 1 warning found.
This is contrary to what's suggested in the Porter's Handbook 
where it says
Keep related variables close together. For example, if using
USE_GITHUB, always put the GH_* variables right after it.
Also see the example Makefile at .
This is fixed in my CVS repo pending the next release.
Fixed in 2.18.5.
(In reply to Joe Marcus Clarke from comment #2)
Thank you, but this fixes only the USE_GITHUB case.
It really was just an example, portlint should also not complain
about USE_PYTHON grouped with related variables, for example,
or USE_WX and related variables, for example,
or any other USE_x grouped with related variables.
See graphics/py-sk1 or graphics/py-gd for example ports where
portlint still just complains about this.
Other examples are ports (graphics/gcolor3, textproc/yodl, ...) using
USE_GITLAB and the GL_* variables.
