I think this is the magic digraph feature of vim that I should probably turn
off because it causes more trouble than good. Thanks for catching that one! :-)

In waf you also don't see that error, because in waf the quota 4B interface
isn't built yet. First we still need to add the strict compile checks (-Werror
flag etc.) which are needed for some configure checks like for the quota and
kerberos tests. There's till some work ahead in that area ...

Cheers
Björn
