Thanks, this is what I was missing!
As expected from the results, in each case, the line is
  /tmp/a\040+\040b	*,szarotka.nabijaczleweli.xyz(ro,root_squash,sync,wdelay=
,no_subtree_check,fsid=3D300,sec=3D1)
with the first fsid=3D exported, except if c was ever exported,
in which case it remains 300.
