In Scheme mode, Emacs font locks the form:
(define (in-vicinity-proc dir)
(lambda (filename)
(in-vicinity dir filename)))
with ‘define’ as a keyword and ‘in-vicinity-proc’ as a function name,
using font-lock-{keyword,function-name}-face, respectively. That's fine.
However, for this form:
(define ((in-vicinity-proc dir) filename)
(in-vicinity dir filename))
then Emacs font locks only ‘define’. I have locally modified
‘scheme-font-lock-keywords-1’ to change "zero or one parens"
to "zero or more parens" and that change seems to DTRT.
Could someone please review the patch below and apply it?

Out of curiosity -- how standard is this? I've never seen such a
definition before.

The bug list would have seemed a better place to post the patch.

I've never seen such a definition before.
Guile supports it. I believe other scheme implementations, too.
The bug list would have seemed a better place to post the patch.
Thanks for the tip; i'll keep that in mind.

Looks ok to me. Feel free to apply it to the trunk yourself.
