[NTG-context] \rotate broken

[Vianney le Clément]

Hi,

The latest beta seems to have broken the \rotate command.

\starttext
\rotate{Test}
\stoptext

gives the following error

! Missing { inserted.

system          > tex > error on line 2 in file test.tex: Missing { inserted ...

1     \starttext
2 >>  \rotate{Test}
3     \stoptext
4
