Fixed formatting errors in rmagic R() docstring...
Fixed formatting errors in rmagic R() docstring Things now mostly render correctly in both terminal and HTML versions of the docs. Note that there are still numerous warnings regarding these magics. At least some of them appear to be from the debauched manner in which the docs are being generated from the @magic_arguments. In addition to the warnings you get when building the docs, if you look at the HTML source for, e.g., rmagic, you'll see that the options are formatted in numerous ways. I get a "--" converted to an en-dash (–) for example. In case you're looking at this in a system that messes up the formatting of the HTML code-point above, the en-dash is 8211.
