Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Looks like defaulting skeleton-untabify to t is no longer a good idea.
There is no way in a skeleton to figure out how many chars are to be
deleted for the skeleton element -num.
So for example, skeletons in sh-scripts can behave abnormally if (setq
backward-delete-char-untabify-method 'hungry).
1. Emacs -q
2. (setq backward-delete-char-untabify-method 'hungry)
3. C-x C-f x.bash
4. C-c : and choose bash
5. C-c (
You should see the function template expanded incorrectly.
I think defaulting skeleton-untabify to nil is the right fix. Otherwise,
the idea that customising backward-delete-char-untabify-method can
implicitly change how skeleton does its work is scary.
A fix local to sh-script.el can be done too:
