Bug#349657: This is a font bug

[Yitzchak Gale <gale@sefer.org>]

I now believe that this is a bug in
the fonts. It is still a mystery to me
why this problem only occurs in the
Debian build, though.

Please forward this bug to
ttf-freefont, and upgrade severity
to important.

In the freetype fonts, the OpenType
feature tag for the Alef-Lamed ligature (0xFB4F)
is "liga", which means "Standard Ligature".
That implies that the ligature is mandatory.

But this ligature certainly should not be
mandatory. The correct feature tag for this
ligature should be "dlig", which means
"Discretionary Ligature". See the OpenType
specification document for Hebrew at:

http://www.microsoft.com/typography/otfntdev/hebrewot/features.aspx

When I make this change in the SFD source
file and recompile using fontforge, the problem is
fixed.
