Subject: Fix SF bug #596434: tweak wordsep_re so "--foo-bar" now splits
X-Git-Tag: v2.3c1~4340
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=cce4d67fc466b902a6b553c731d7be700b506dfd;p=python

Fix SF bug #596434: tweak wordsep_re so "--foo-bar" now splits
into /--foo-/bar/ rather than /--/foo-/bar/.  Needed for Optik and
Docutils to handle Unix-style command-line options properly.
