Describe the bug
a little bug abount formulas by space word after TBLFM;

<!-- TBLFM: @3$1..@>$1=(@-1+1) -->

1. specially! there must be a space word after TBLFM, if not, the parser cannot parse the one.
2. this bug is so tiny, and very very difficultly to discover.
3. I think maybe the space word is not necessary.

Expected behavior

1. After TBLFM, space is not necessary.

Looks like this could be changed on this line, but I need to think about the implications of that change first and decide whether to make it or not.
