Can PORTVERSION be gYYYYMMDD ?

[Yuri]

The port audio/ir-lv2 was committed with PORTVERSION=g20130909.


make in another port with this instruction:

 > RUN_DEPENDS=ir-lv2>0:audio/ir-lv2
doesn't check the version of ir properly, and always tries to rebuild it.


Is PORTVERSION=gYYYYMMDD actually allowed?

The handbook doesn't mention such format. Section Example 5.9 here 
https://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/makefile-distfiles.html#makefile-distname-ex1 
offers PORTVERSION=20160710 as an example.

If it's not allowed, why doesn't framework complain?

Otherwise, the version check for such ports must be fixed.


Thanks,

Yuri
