The following exports as a normal call line
#+call: double(it=0)

Now here is an inline call call_double(it=1) stuck in the middle of
some prose.

This one should not be exported =call_double(it=2)= because it is
quoted.

Finally this next one should export, even though it starts a line
call_double(it=3) because sometimes inline blocks fold with a
paragraph.

And, a call with raw results call_double(4)[:results raw] should not
have quoted results.

The following 2*5=call_double(5) should export even when prefixed by
an = sign.
