emacs -Q
Go to (elisp)Example Major Modes
 
The `emacs-lisp-mode-syntax-table' example is not indented
correctly.  E.g.:
 
   (while (< i ?0)
(modify-syntax-entry i "_   " table)
(setq i (1+ i)))
 

In GNU Emacs 23.1.1 (i386-mingw-nt5.1.2600)
 of 2009-07-29 on SOFT-MJASON
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (4.4)'

I can't reproduce this: the indentation is correct for me.

Well, it's as clear as day for me, in emacs -Q on Windows. Perhaps it's a
platform problem.

It appears just as is written above. The calls to modify-syntax-entry and setq
are not indented underneath the while - they are outdented wrt the while.

No, it wasn't.  I fixed it.  Thanks for catching this.

I don't know why Yidong didn't see it; perhaps he was looking at the
Texinfo sources, where the example's indentation is indeed all dandy.
The problem was that this example used TABs, not spaces, for
indentation, which is generally a no-no in Texinfo (that's why Texinfo
mode sets indent-tabs-mode to nil).  When an Info file is produced,
makeinfo indents examples some more, and then indentation with TABs
gets screwed, of course.
