[nsd-users] nsd v4.3.5 treats long used DKIM line as syntax error

When I upgraded from nsd v4.3.4 to v4.3.5, nsd-checkzone(8) started
flagging errors in my zone files for DKIM lines that had been there for
many years.

Here's roughly what the line looks like:

    example._domainkey IN      TXT     ( "v=DKIM1; k=rsa; " "p=ZvtSzN0TPFdTFVo3QDRONDHNN4TANQPOvDXOtDDAqEOEObihifWVD095LxDXbSYILzbHBWCPuPzhzzxlS+tnLcTe+VcpZrh4TkFxym+++nZ8tBL1aR1agdd27lmo2GmRc84gXJUIlqu4Ml0TL/Ifxsuc4pJxD9sOO4FotjBnyTUI8wn3rWD5bVBjWzzLDr0ioP8W67TSxGblDmjhA//9WidNDNO")

(Values have been changed to protect the innocent.)

Is there some syntax error in the above line, or is this a bug?

FWIW, I'm running on FreeBSD 12.2, and here's the output from nsd:

    $ nsd-checkzone example.org example.org.m4
    [2021-03-08 12:13:18.298] nsd-checkzone[96109]: error: example.org.m4:124: syntax error
    zone example.org file example.org.m4 has 1 errors
