sequence of <em>'s is mis-rendered in some cases.

[leeoniya]

by itself,

#### *expression<sub>1</sub>* *expression<sub>2</sub>* ... *expression<sub>n</sub>*

renders correctly as

<h4><em>expression<sub>1</sub></em> <em>expression<sub>2</sub></em> ... <em>expression<sub>n</sub></em></h4>

but in the context of https://raw.github.com/dmajda/pegjs/master/README.md renders as

<h4><em>expression<sub>1</sub></em> / <em>expression<sub>2</sub></em> / ... / <em>expression<sub>n</sub></em></h4>

maybe a parser issue?
thanks!

I think you're looking at it wrong. This is probably best explained by some commandline examples.

$ marked readme.md | grep sub
...
<h4><em>expression<sub>1</sub></em> <em>expression<sub>2</sub></em> ... <em>expression<sub>n</sub></em></h4>
<h4><em>expression<sub>1</sub></em> / <em>expression<sub>2</sub></em> / ... / <em>expression<sub>n</sub></em></h4>

$ cat readme.md | grep sub
...
#### *expression<sub>1</sub>* *expression<sub>2</sub>* ... *expression<sub>n</sub>*
#### *expression<sub>1</sub>* / *expression<sub>2</sub>* / ... / *expression<sub>n</sub>*

There are two separate locations for that heading. One has slashes, one doesn't.
