getbufvar accepts only two arguments in Vim 7.3 (at least the one
included in OS X 10.11.5), and returns an empty string when the buffer
or variable does not exist: getbufvar({buffer}, {variable}).
Vim 7.4 has extended the built-in function so that it additionally
accepts an optional argument which determines the default return value:
getbufvar({buffer}, {variable}, [, {default}]). When the third argument
is not given and the buffer or variable does not exists, getbufvar
returns an empty string as before.
getbufvar({buffer}, {variable}) works in both Vim 7.3 and 7.4, and is
practically equivalent to getbufvar({buffer}, {variable}, 0) because an
empty string is coerced to 0 if necessary.
