Comment (by Isaac Dupree):
okay, seems reasonable, although I suppose there could also be command-
line flags to modify the behavior
- at least, an option for if someone wants the sources of all dependencies
that are on Hackage, even if installed, otherwise they'll be hard to get
- or all packages that are not fully upgraded. For example, if you have
internet connection for a short time and it'll take your computer a while
to build all of them. In this case, we want the newest versions. But if
you want to look at the sources, it's also likely that you'll want to look
at the currently installed versions' sources :-)
but ignoring those additional features:
hmm, it's been a while since I looked at the Fetch code, but IIRC it
looked not too hard to make the simple change to default to do C, for
someone familiar with those types -- don't count the package itself as an
*installed* dependency.
