Equation Numbering bug?

Equation Numbering bug?

[Aditya Mahajan]

I do not understand why the second equation is numbered

\starttext
   \placeformula \startformula \startalign[n=2]
     \NC  a \NC = b \NR
     \NC  c \NC = d \NR[+]
   \stopalign \stopformula
   Some text to separate equations
   \startformula
     e = f
   \stopformula
\stoptext

I can get rid of the numbering by placing a \placeformula[-] in the 
begining. But, it should not be numbered by default.

It is a bug. \placeformula turns on formula number processing
(\settrue \handleformulanumber), but it never resets it.

I guess this could be done right at the end of each formula,
like so:

\unprotect
\def\dostopformula
   {\doplaceformulanumber
    \getvalue{\e!stop\formulaparameter\c!alternative\v!formula}%
    \resetlastlinewidth
    \nonoindentation
    \dochecknextindentation{\??fm\currentformula}%
    \egroup
    \setfalse\handleformulanumber %TH, new
    \dorechecknextindentation}
\protect

Hans, I am not completely sure this is the right place. Please check!

Cheers, Taco
