Yes, sorry.

Partially, but still

ghc-compiler    x86_64     7.6.3-18.3.el7       epel     15 M

matej at mitmanek: ~$ du -hs /usr/share/doc/ghc/html/
20M    /usr/share/doc/ghc/html/
matej at mitmanek: ~$ 

(When installing just ghc-compiler on a computer where no ghc-* package
was).

So probably /usr/share/doc/ghc/html should be owned by ghc-base not
ghc-compiler, shouldn't it?

Couldn't this be somehow scripted?

Anyway, being bound to install tens of megabytes of completely useless
documentation just because I want to run rpm --rebuild pandoc*.src.rpm
is really crappy user experience, which really doesn't makes me
interested in further investigation of the Haskell universe.
