Description Carl Fürstenberg 2006-10-28 23:18:15 UTC
The syntax of underbrace etc. is broken, resulting in sub and superscrips
getting wrong placement. Also the construct array is missing, which is needed to
be able to construct equations that is not always centered.

Patch is made, adressing this issues.

Comment 2 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-10-28 23:21:35 UTC
Maybe you could explain the exact problems with the current behavior, and why
they're incorrect?
Comment 3 Carl Fürstenberg 2006-10-28 23:22:58 UTC
for "\underbrace{0\dots2}_4" the current effect is that the "4" is placed as a
"normal" subscript, instead of below and centered under the brace.
Comment 4 Aryeh Gregor (not reading bugmail, please e-mail directly) 2006-10-28 23:33:12 UTC
And do you have a source for the latter behavior being the correct one?
Comment 5 Carl Fürstenberg 2006-10-28 23:34:57 UTC
the current parser replaces the code "\underbrace{0\dots2}_4" with
"{\underbrace{0\dots2}}_4" which makes it impossible to utilize underbrace etc
to it's fully.
