bug

Tabs are not handled properly anymore, which makes it difficult to format CommonMark source code properly.

Example 1

Using a tab to indent contents of a list does not work. It appears to be treated like one space. This is in conflict with the CommonMark specification. For example,

*——⇥test
———⇥
———⇥test

renders as:

• test

  test

while it should render as:

• test

  test

Example 2

Tabs in code environments are bluntly substituted by four spaces instead of making a four-space indentation. For example,

———⇥*——⇥test
———⇥———⇥test

renders as:

• test test

while it should render as:

• test test
