tweaks: do not use 'switch' when there are just two possibilities 

Also, remove an unneeded 'if', as parse_escape_sequence() is only
ever called when there are at least two bytes after the Esc code.
(If there were not, the 'for' loop after calling convert_sequence()
would use an uninitialized 'consumed' value.)
