2020-12-20	Move browser command formatting to a new `fmtBrowserCommand()`	Teddy Wing
	Not to be confused with the previous `fmtBrowserCommand()` function, this one handles all formatting including `%s`, shell escaping, etc.
2020-12-20	Rename `escapeBrowserCommand()` to `shellEscapeCommand()`	Teddy Wing
	Didn't like `escapeBrowserCommand()` either, since we're escaping the URL not the rest of the command.
2020-12-20	Rename `fmtBrowserCommand()` to `escapeBrowserCommand()`	Teddy Wing
	Formatting the browser command will incorporate more steps, not just this one, so rename it to be more specific about what it's doing. I want to use the other name for a different function.
2020-12-20	Escape single quotes in URL	Teddy Wing
	On Unix, we escape the URL argument by surrounding it with single quotes. This fails if the URL contains single quotes. It also fails if the `BROWSER` command contains `%s` not surrounded by single quotes. Fix this by escaping the single quotes. We might also want to look into passing the `BROWSER` command and arguments into `exec.Command` directly instead of through `/bin/sh` and checking if that has an automatic escaping mechanism we can take advantage of.
2020-12-20	Handle `%s` format string for URL in `BROWSER` variable	Teddy Wing
	The `BROWSER` environment variable might contain a `%s` format string that should be replaced by the URL to open. If it's present perform the replacement. Otherwise, append the URL to the `BROWSER` command as before.
2020-12-19	Add `BROWSER` support to `OpenReader()`	Teddy Wing
	If the `BROWSER` environment variable is set, open the reader in the given browser. Works by copying the `Reader`'s contents to a temporary file and opening that with `OpenFile()`.
2020-12-19	Add `BROWSER` support to `OpenFile()`	Teddy Wing
	If the `BROWSER` environment variable is set, open the given file path in the given browser.
2020-12-19	Add `BROWSER` support to `OpenURL()`	Teddy Wing
	If the `BROWSER` environment variable is set, open the given URL using the command specified in the variable. Run the command in a shell process, either from the `SHELL` environment variable or `/bin/sh` on Unix OSes. Run it through `cmd` on Windows. Essentially repurposes my code from https://github.com/pkg/browser/pull/14.
2020-12-14	Wrap `github.com/pkg/browser` in a new `browserenv` package	Teddy Wing
	This will be used to extend `browser`'s functionality.
