Font problem with TL'20

[David Carlisle]

In a local copy change line 91 from

  \def\zw at isbnfont{\usefont{OT1}{phv}{mc}{n}\fontsize{\zw at isbnfsize
}{\zw at isbnfsize}\selectfont}}

to

  \def\zw at isbnfont{\usefont{OT1}{phv}{c}{n}\fontsize{\zw at isbnfsize
}{\zw at isbnfsize}\selectfont}}

deleting the `m`  the interpretation of mc has changed, normally it will
manage to default to the right thing with a warning but here the condensed
form needs c explicitly otherwise it falls back on the  medium m and the
letters are too wide.
