When trying this with a simple c-program, it seems the `align' function
has changed behavior since 24.3; it no longer (by default at least)
gives at least one space, and in some cases actually breaks the code by
concatenating the type and variable name. E.g. write some like this
(after emacs -Q test.c)
int foo (int bar)
{
char flub;
}
now mark the 'char flub' line, M-x align and we get:
int foo (int bar)
{
charflub;
}
which gcc doesn't really appreciate. In general it seems that align does
not insert at least one space between type and variable in c-mode.

This is broken by defaulting tab-stop-list to nil in revno: 114577.
Stefan, can I fix it as follows in emacs-24? Thanks, Leo.

Hmm... I guess it's OK, yes. Thanks,

I think there is a smilar issue with ruler-mode. Compare:
emacs -Q --eval '(setq ruler-mode-show-tab-stops t)' -f ruler-mode
in 24.3 (tabs marked) and 24.3.91 (no tabs marked).
Leo, any chance you could fix that one too?
There are a handful of other files that use tab-stop-list;
it would be good to check them too.

I did a grep in lisp/ and these are the files using tab-stop-list:
- woman.el
- progmodes/asm-mode.el
- ruler-mode.el
- textmodes/picture.el
The following patch seems to fix all except woman.el. woman.el seems to
use its own interpretation of tab-stop-list i.e. it may not be affected
at all by the change to tab-stop-list. Comments? Leo
