Feature request: bug and user_notes keywords

[gwright@…]

In my portfiles I use two keywords to give the maintainer and user some useful information. For now, I comment them out. The keywords are 'bugs' and 'user_notes'.

'bugs' is intended to tell the maintainer about infelicities in the port. This might include delicate hacks needed to get it running or unsupported features.

'user_notes' is usually a reminder that the user has to do something to get the expected behavior, like set an enviroment variable. It can also warn of pitfalls for the unwary.

The 'user_notes' variable could be displayed at the end of installation from the command line, or in a text window from the GUI version. Maintainers (and other knowledgable users) can be expected to grep for 'bugs', but it might be nice if the GUI supported display of the 'bugs' value for advanced users.

These seem to be both useful and unlikely to break anything. Could they be added to the port system?
