Copying the test plan from the bug report:

A.
1) have $a active in one of the linking fields (like 461, 463, etc.).
2) have a biblio record with the field 700 $a, $b, $f filled up
3) go to cataloguing -> field 4XX of your choice, use the plugin to
  fetch data from biblio rec. mentioned in 2)
4) see the punctuation in $a -- it will be wrong (no closing bracket)

B.
1) have $a active in one of the linking fields (like 461, 463, etc.).
2) have a biblio record with the field 700 $a, $b, $c, $f filled up
3) go to cataloguing -> field 4XX of your choice, use the plugin to
   fetch data from biblio rec. mentioned in 2)
4) see the punctuation in $a -- it will be wrong (dash instead of
   semicolon between original $c and $f, no closing bracket)

C.
1) have $a active in one of the linking fields (like 461, 463, etc.).
2) have a biblio record with the field 702 $a, $b, $c filled up
3) go to cataloguing -> field 4XX of your choice, use the plugin to
   fetch data from biblio rec. mentioned in 2)
4) see the punctuation in $a -- it will be wrong (unnecessary semicolon
   after original $c, n.b. lacking space).

D.
1) have $a active in one of the linking fields (like 461, 463, etc.).
2) have a biblio record with the field 712 $a, $b filled up
3) go to cataloguing -> field 4XX of your choice, use the plugin to
   fetch data from biblio rec. mentioned in b)
4) see the punctuation in $a -- it will be wrong (unnecessary opening
   bracket at the end).

Test plan, all tests and QA script pass.
Thx Bernardo for his testing and explanations!
