I have a bibtex entry that has a long URL

    @Misc{DelhiPlasmaPyrlosis,
      author       = {Central Pollution Control Board, India},
      title	       = {Study on Plastic Waste Disposal through ``Plasma
                      Pyrolysis Technology''},
      month	       = {oct},
      year	       = 2016,
      note	       = {\url{https://cpcb.nic.in/displaypdf.php?id=cGxhc3RpY3dhc3RlL1BsYXNtYS1QeXJvbHlzaXMtZmluYWwtUmVwb3J0LTIxLTExLTE2LnBkZg},
                      last checked on 15/08/2023.},
      file	       = {papers/delhiplasmapyrlosis.pdf},
      url = {https://cpcb.nic.in/displaypdf.php?id=cGxhc3RpY3dhc3RlL1BsYXNtYS1QeXJvbHlzaXMtZmluYWwtUmVwb3J0LTIxLTExLTE2LnBkZg}
    }

When I fill the entry with C-c C-q, url lines becomes

      url	       =
                      {https://cpcb.nic.in/displaypdf.php?id=cGxhc3RpY3dhc3RlL1BsYXNtYS1QeXJvbHlzaXMtZmluYWwtUmVwb3J0LTIxLTExLTE2LnBkZg}

This however breaks the buttonisation since the second character class
in bibtex-font-lock-url-regexp does not include newline, only space and
tab.  If I add a newline as below, then the url field value is
buttonised as expected.  Should this be done in bibtex-mode.el as well?
