2000-05-05 Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr>
* src/text.C (draw): do not display an exclamation mark in the
margin for margin notes. This is confusing, ugly and
uninformative.
* src/LaTeXFeatures.C (getPackages): load amssymb also when 'Use
AMS math' is checked.
* src/buffer.C (makeLaTeXFile): do not depend on the textclass
name to see whether including the amsmath package is needed.
2000-05-05 Dekel Tsur <dekel@math.tau.ac.il>
* src/paragraph.C (validate): Compute UsedLanguages correctly
(don't insert the american language if it doesn't appear in the
document)
* src/paragraph.C (TeXOnePar,SimpleTeXOnePar,SimpleTeXSpecialChars)
The argument of \thanks{} command is considered moving argument
* src/paragraph.C (SimpleTeXOnePar): Put \protect before \\ if in
moving argument.
2000-05-04 Dekel Tsur <dekel@math.tau.ac.il>
* src/text.C (GetVisibleRow): Improved drawing of vertical lines
for appendix/minipage/depth. The lines can be now both in the footnote
frame, and outside the frame.
* src/text.C (SingleWidth,draw): Correct rendering of Hebrew vowels
points ("nikud")
2000-05-05 Juergen Vigna <jug@sad.it>
* src/table.[Ch]: removed the inset and buffer stuff as this is now
