Saluton, Moin,

sh-script-mode has evolved heavily since I wrote it.  Since I've shunned Shell for Perl, there's no point in me being maintainer any more.

Cannot reproduce with current CVS.

shell-script-mode seems to require font-locking to indent correctly --
anyway I can reproduce the problem if I turn off font-lock-mode, whereas
things work fine if it's turned on.

I think the current shell-script indentation foo is due to Stefan BTW.

Maybe this sort of problem could be fixed by having shell-script-mode force
on font-locking in its individual buffer, but disable the display effect when
the user hasn't turned on font-lock-mode (e.g., using
`char-property-alias-alist').  Stefan?

I'm not sure what you mean by `foo', but you're probably right.

Yes, that's the plan, but it hasn't been realized yet.
Using `char-property-alias-alist' is something I had not considered yet.
My grand plan is to decompose the font-lock info provided by a mode
so that it can be turned on/off piecemeal.  This would provide also
a replacement for font-lock-maximum-decoration (which seems not
to be used by anyone except for those who don't know that setting
it to t is unnecessary).
If anybody wants to do it before I get to it, that would be wonderful.

One of the underlying questions is: why do people not turn on font-lock ?
Is it only because they don't like the colors (I have customized my faces to
be a lot more subdued, with most of them reduced to being identical to
`default')? is it because of slowdown? something else?

One data point: my co-worker claims he finds the colors distracting and
"headache inducing" and always makes me turn them off when he's looking
at my screen.  (Which is unfortunate, because my eyes glaze over without
them.)

No, it's not an insult.  :-)
I just meant `stuff.'
