Bug in treatment of spaces in mathmode mkiv

Bug in treatment of spaces in mathmode mkiv

[Otared Kavian]

Sorry for reposting this message sent this morning: I thought it  
didn't go through…

Hi Hans,

I noticed that in math mode the spacement of some symbols are  
incorrect while using mkiv (they are correct in mkii).
Here is an example

%%%%% begin example

\starttext
Set $a := bc^{-1}$.
\stoptext

%%%%% end example

In this example, there should be a space before and after ":=" as one  
may see it readily in mkii (and indeed in plain TeX…).

Best regards: OK

in char-def.lua both colon and equal should be 'relation'

note for aditya: we need to check more of them (more colons)

Thanks Hans: it is fixed now with the latest beta mkiv.

Do you mean other instances of colons used in math mode?

colon needs a bit more care. The literal : should be a mathrel, while 
\colon should be a punctuation. I do not know how to set this using 
mathspec.

equal in the current char-def is wrong. The mathclass should be relation 
(rather than binary).

hm, we had two mathname=colon's, so i removed the 0x003A
