hg up -C seems not to work

[Uwe Brauer]

Hi 

I am very confused

 hg status gives me:

M VennDiagram/new.org

So I run as always

 hg up -C

1 files updated, 0 files merged, 0 files removed, 0 files unresolved

But 

Hg status continues to give me

hg status
M VennDiagram/new.org


What is up here?

I could run 

hg shelve 

But I am confused and want to understand what's up here.

Thanks

Uwe Brauer
