[21.5] Support builtin functions in find-function (crash in C-h f)

Adding 1 to the dimension of buf fixes the crash for me. Please review and make sure that's everything. diff --git a/src/ChangeLog b/src/ChangeLog index cdf3be7..536e1df 100644 --- a/src/ChangeLog +++ b/src/ChangeLog ＠＠ -0,0 +1,4 ＠＠ +2006-05-02 Stephen J.
