bold on f and zeta since they are vectors

[navidcy]

I made f and zeta bold. (\mathbf has no effect on greek letters so I used \boldsymbol)

One remark: why g^{'} and not simply g'? The prime gets rendered so high up with ^{'}.

@edoddridge: Note that this PR is to be merged on your doc-fixes branch. Also, I only changed lines 63, 66. All other changes below must have to do with how are text editors handle line breaks. (It's been puzzling me long e.g. when interacting with @glwagner; if you have any idea why that happens let me know..)

@navidcy it might be how your text editor handles whitespace, not line breaks.

I have noticed some funny stuff with line breaks that occurs when one person uses Windows and another uses Mac, though.

[navidcy]

Indeed, it was atom:whitespace package's fault... I disabled the package. Thanks, @glwagner.

LGTM. Thanks @navidcy and welcome to the contributors list 🎉

One remark: why g^{'} and not simply g'? The prime gets rendered so high up with ^{'}.

Because that's what I started doing, but you're right - it looks better as g'.
