I really do like

DESCR=Some relatively short amount of text that describes the port \
       in more detail than COMMENT can do. This could be multiple \
       sentences and broken across lines.

We have multi-line entries all over the place with things like long 
commands in pre- and post-install targets.  Since pkg-descr tends to be 
a write-once file, I think it's a pretty tiny amount of pain for shaving 
off that many files.  If you're really are worried about making 
maintainers do non-natural line breaks for readability, add a "make 
reflowdescr" target or add something to porttools that does it for us.

The reason I like having this stuff in the Makefile is that you can do 
something like this:

# make -C /usr/ports/foo/bar -V DESCR

Could we do something similar to dependency lists?  For example:

DISTINFO= example1.tbz:size:{SHA256}hash \

In the simple case where DISTFILES is one generated filename:

DISTINFO= ${DISTFILES}:size:{SHA256}hash
