Hello,
I use emacs in viper-mode and font-lock-mode and have been very happy
with that set-up for ages. I was surprised to see it malfunction
today in a tiny corner case.
Here's a minimal test case:
printf '#define f(x,s) \\\n' > /tmp/k.c
emacs -Q -f viper-mode -f font-lock-mode /tmp/k.c
Hit "n" to get past the viper-mode prompt,
then "fx" to position the cursor on the "x".
Here's the interesting part. The cursor is on the "x"
and say you want to change "x,s" to ",":
#define f(x,s) \
^
One way to do that is via "3s", then hit "," and "ESC".
That is supposed to leave you with this:
#define f(,) \
But it mistakenly produces this:
#define f(,x,s) \
That I choose to include "," in the replacement string is critical.
Without that, it works fine. It also works fine if you don't use
font-lock-mode.
This was using the very latest, just built from emacs.git.
Here's the most recent commit:
