[Freefont-bugs] [PATCH] Remove math constructions that do not have glyph extenders

[Frédéric WANG]

Hi Steve,

Per the feedback by Jonathan & Khaled, math constructions without glyph
extenders are invalid so the attached patch removes them. However, we
probably want to add larger variants for slash, backslash, and
left/right angle brackets...
