FontForge ignores second lookup flag when merging feature info file with multiple flags.

Example feature file:

lookup Kern_HEBR {
  lookupflag RightToLeft IgnoreMarks;
    pos \afii57645 \afii57681 -10;
    pos \afii57645 \afii57664 -10;
} Kern_HEBR;

feature kern {

 script hebr;
     language dflt ;
      lookup Kern_HEBR;
} kern;

After the import the lookup metadata shows just the first flag set:

The issue seems to be in fea_ParseLookupFlags()
