Use https links in user-facing startup and error messages
I consider myself lucky that in my circle of friends, http urls (as
opposed to https urls) are frowned upon in that we generally
apologize in the rase cases that we share an http url.
This pull request changes http links into their https analogues in
the following places:
- In the GHCI startup message (and parts of the User's Guide, where
there are verbatim transcripts of GHCi sessions).
- In a couple of error messages, asking the user to report a bug.
(I also took the liberty to change a single space before the reportabug
url into two spaces, harmonizing this occurence with the others.)
I'm not trying to start a war. I just had a moment to spare and felt
like preparing this diff. Merge or don't merge as you wish!
