[PATCH 1 of 1] subrepo: check for dirty warns on missing revision instead of abort

[Friedrich Kastner-Masilko]

Zitat von Matt Mackall <mpm at selenic.com>:

Changed that here, thanks for the update. It worked with .node(), too.

The previously written statement still applies, though. No warning on  
"hg update" to a changeset containing the same subrepo hash. I guess  
this is because the .hgsubstate is not in the applyaction-list and  
thus the subrepo-system is not touched besides evaluating dirty() .
