In the current trunk the indentation for bash scripts looks as in this
test case:
$ cat test_indent.sh
#!/bin/bash
if [ "${foo_a}" != "${foo_b}" ]; then
if [ "${foo_c}" = "${foo_d}" ]; then
echo
echo "Hello..."
echo
exit 1
fi
fi
The inner if-fi looks ok but in the outer one expects the last fi under
the first if.. Or not?
This happens with
$ emacs -Q &
and using TAB to indent..
Ciao,
Angelo.

This works correctly if you use (setq sh-use-smie t) which I recommend.
It is currently not the default setting because it doesn't yet support
all the indentation-config variables of the old indentation code, and
doesn't support the "guess indentation settings" feature either. But in
most other respects it should work "as well or better".

It works fine in 24.3 out-of-the-box.

Also in trunk rev. 114585 (09 October 2013). So, some recent changes
have broken the indentation of Shell-script[sh] mode...
Ciao,
Angelo.

Why, by default, the last "fi" should be under the previous and not
under _its_ "if"? Should "indent" mean that the matching if-fi, {-},
begin-end, if-endif etc. start the same column?
Instead the test case shows that all statements after the first "if"
if [ "${foo_a}" != "${foo_b}" ]; then
are considered belonging to its block statements. All the next formatted
code is lost.
This should be called "regression"..
Ciao,
Angelo.

By experiment, reverting the "Always setup SMIE..." part of your
2013-10-11 change fixes this regression.

Aha! I'll try and see why that introduces such breakage.
Probably a call to backward-sexp somewhere.

This specific problem seems due to smie-setup's
(setq-local forward-sexp-function #'smie-forward-sexp-command)
