Re: pre-abbrev-expand-hook

[Richard Stallman]

The example was no good; it should test last-command-char rather
that (preceding-char).

I discovered that pre-abbrev-expand-hook is useless with the current
C code, since it is run whether or not the previous word
is an abbrev.  This change seems to make it usable.
