[environment] Fix url-quote-magic

`url-quote-magic` automatically escapes characters that fit a URI scheme
as you type. From what I can tell from the commit history, this was
mistakenly placed in `else` branch of the nested conditional instead of
at the end of the outermost conditional.

Closes #160
