Problem when rendering markdown files

Hi,

We have found an issue when Bitbucket is rendering markdown files (eg Readme.md) files. We do not know if it is a browser problem or a server problem.

We were designing our "readme.md" files using Intellij and Atom. If we use spaces (0x20) for creating nested bullet-point list, the rendering in Intellij and Atom works correctly. But when we push the code to bitbucket , the nested bullet-points list are nor rendered correctly.

See the following example with spaces (0x20)

• hi

• • hi
  • hi2
• hi

Then if we use tab char (0x09) instead of space (0x20) the render is correct on both Intellij ,Atom and bitbucket. See the following example that use tabs (0x09)

• hi

• • hi
  • hi2
• hi

Using both Google Chrome and Firefox, is not possible to insert tab char using tab key, within the web editor of bitbucket.

It would be nice if bitbucket could render nested bullet point lists, as Intellij and Atom does.
