Howdy,

Just took 28.0.91 out for a spin, and I like that it seems much more
responsive.

However, lots'o bash gets written here, and one of my idioms is:
<code>
if test;then
   do something
fi
   ^
</code>

In emacs-28, when I type the 'fi', the start column is still indented,
point is placed in column 4.

If 'then' gets moved to the line *after* 'if test',
OR
if a space is inserted between the ';' and 'then', '; then'
<code>
if test; then
</code>
it's all good again and point is set correctly at column 1.

<code>
if test
then
    :
fi
^
</code>

OR

<code>
if test; then
    :
fi
^
</code>

CONFIGURATION NOTES:
The settings for sh-mode all appear to be at the defaults, and a check of
my init code only shows
<lisp>
(setq sh-shell-path "/bin/bash"
      sh-find-file-modifies nil)
</lisp>


On further observation, it seems the smie engine thinks the code which is
legal bash has a syntax error, which would be the missing whitespace
after the ';'.  I can see this by the block start not being highlighted
when at the end of the block (the final 'fi' in the if-else-fi) when the
space is missing after the ';', which "heals" when the space is inserted.

Thanks for looking into this.
