I don't know if anyone feels the same, but I'm not happy with the spacing of commas in math mode (pictures attached). For instance, typesetting H^1(X,F), the comma seems to be closer to the F than to the X. Equal spacing on both sides or setting the comma closer to the X are I guess a matter of taste (inserting a \neghairspace after the X achieves the latter). In any case, I would kind of prefer equal spacing.
\setupmathematics[autopunctuation=no] @Hans: I would suggest that this should be made the default.
Also, it seems odd that adding a negative space \neghairspace does not change the length of the total formula - I had expected the modified one to be slightly shorter...?
I don't know about this.
On a related issue, the spacing for lists, e.g. (0,0,...,0), is not satisfactory. LaTeX provides a command \dotsc for dots between commas (and other commands like \dotsm, \dotsi, \dotsb). I don't know if all of these are necessary, but \dotsc and its cousins are not defined in ConTeXt and both using \ldots or just ... give unsatisfactory results. (It is also curious that the spacing after the first comma and the spacing after the last comma in (0,0,...,0) is evidently different...) Personally, I think I favour something approximating (0, 0, ..., 0) and I find \ldots is spaced too widely, ... too closely, and in any case, the spacing of the dots doesn't match with the spacing of the commas.
Any second opinions?
Adding the \dots(m|i|b|) etc from amsmath is a good idea. I will look into that.
P.S.: I'm also confused about \colon and : - the latter looks better to me in $i: A \to B$. The spacing for projective coordinates [1:0: ... :0] is wide but still acceptable. The index of a subgroup |G:H| is far too widely spaced, but \colon only gives asymmetrical spacing. The semicolon seems to undergo the same spacing as the comma, with the same problems mentioned above.
I think that the spacing of $i \colon A \to B$ is correct. (Compare from plain TeX output). I don't know what do you expect from |G:H|. : is defined as a relation and \colon is defined as a punctuation. Does |G{:}H| look better? (which forces : to be a math ord).
P.P.S.: \hairspace does not seem to have any effect in math mode, while \neghairspace does. Bug or feature?
Don't know. Aditya
