Bug#297649: better documentation of "dynamic mmap ran out of room" error

[debian-bugs@brisammon.fastmail.fm]

Package: apt
Version: 0.5.28.5

There's already a couple of bug reports requesting that this be fixed, but I 
didn't find any requesting that this long-standing issue be documented.

I would suggest something in /usr/share/doc/apt or in the error message itself 
that tells users that the fix/workaround for this problem is edit the 
Cache-Limit variable in the apt.conf config file.

Perhaps the patch submitted to the deity list a little while back:
