[Trac] InterTrac and RST links

[Emmanuel Blot]

Hi,

What would be the RST syntax to create a link to a wiki page of
another Trac project?

For an "intra-wiki" page, the link syntax is:
  `WikiPage`:trac:
However, the InterTrac wiki syntax does not seem to work from RST:
  `project:wiki:WikiPage`:trac:
does not get interpretated as expected.

Thanks,
Manu
