Sun's straight from the CGA set.

I wasn't satisfied with the way commas and apostrophes look when clustered up together, as they frequently are in certain map areas. Moving the apostrophe over one pixel (which I should have already done according to my alignment rules) helped break them up visually, but it occurred to me that they should probably have differentiation of form as well, in case there's some situation where it's important to know which one you're looking at without a lot of nearby context to quickly nail down its vertical position. The Acorn and C64 fonts both use angular straight quotes, but those weren't really satisfying either... looked too much like slashes. On a whim, I decided to check which form is used by the Windows Fixedsys font. Apostrophe is an uninspired vertical tick, but the backquote is a glorious hybrid of the CGA and Acorn/C64 forms! I have embraced it wholeheartedly; image updated above.
