Subject: * src/lread.c (read0): Don't allow radix 0 or 1.
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=91169d706a1b503f47b7f1f454977ee6e80f95db;p=emacs.git

* src/lread.c (read0): Don't allow radix 0 or 1.

This was just a silly mistake introduced in Emacs 29.  Found by Pip Cet.

(cherry picked from commit e888bd990dcc82690ae33052f2aaec3ca827960c)
