* modules/bibconvert/lib/bibconvert.py: Fixed a bug concerning
empty fields. Functions attached to fields are no longer ignored
when the field has no value.
E.g. Consider the following line: 300---<datafield tag="300"
ind1=" " ind2=" "><subfield
code="a"><:Num::Num:><:Num::Num::IF(,mult. p,
p):></subfield></datafield> If there is no value for the field
"Num", the desirable output is: <datafield tag="300" ind1=" "
ind2=" "><subfield code="a">mult. p</subfield></datafield> However,
this did not work - when Num had no value, the function (IF in this
case) was ignored and the line was not printed. This has been
fixed. Also now, given the following template line:
300---<datafield tag="300" ind1=" " ind2=" "><subfield
code="a"><:Num::Num:><:Num::Num::IF(,, p):></subfield></datafield>
If the value of Num is "33", the following will be printed:
<datafield tag="300" ind1=" " ind2=" "><subfield code="a">33
p</subfield></datafield> If however Num has no value, the line will
not be printed. This is because the "IF" function will return
nothing, and it is considered undesirable to print the line.
