Before:
{{var}} -> {var}, but the regex matches at the inner brace, but
re_replace returns the whole match (match.group(0) = "{var}") unchanged, passing
"{{var}}" to Formatter.
{{defined_var|def}} -> {{defined_var}}, because the regex matches at the
inner brace and re_replace returns "{%s}" % key ("{defined_var}"), passing just
"{{defined_var}}" to Formatter.
{{undefined_var|def}} -> exception, because the regex again matches at
the inner brace and re_replace returns default ("def"), passing "{def}"
to Formatter which then fails as def is not a defined variable (assuming
it isn't and allow_empty = False).
{{undefined_var|defined_var}} -> value of defined_var, same as above,
"{defined_var}" is passed to Formatter.
By preventing the regex from matching at inner braces, none of these
weird cases happen and even-braced strings are passed to Formatter
unmodified.
