The method that was being used to read the header from the input was
inadvertently dropping the first non-header line on the floor; although
this happens to be okay in some cases (where there is an empty line
after the header) in the case of newer versions of the
ScriptExtensions.txt file, this was causing the generated code to be
missing the first entry, for U+00B7 (MIDDLE DOT)
