[issue3917] set_display definition allows empty '{' '}' in Language Definition

[Georg Brandl]

Georg Brandl <georg at python.org> added the comment:

Thanks, fixed in r66522. Also removed the last two paragraphs of the set
display explanation which were pasted from genexps and made no sense,
and added a sentence about {} not constructing a set.

----------
resolution:  -> fixed
status: open -> closed
