hgweb: replace next(revs) to revs.next() to fix compatibility with Python 2.5-

tests: glob out exception type for directory collision Got three different results on buildbot.

record: add checkunfinished support (issue3955)

checkunfinished: accommodate histedit quirk Turns out histedit actually intends for commits (but not other operations like update) to be possible during its operation.

tests: test-check-code-hg.t works for all files to check with xargs, backslashes are eaten up. Convert them to slashes therefore. This is only a problem with ls (on windows). hg manifest returns slashes. The pipe char is moved before the line end for telling check-code.py that sed does not modify the output.

check-code: do not abort on an unreadable file, only report this

heads: fix children/descendants in doc (issue3992)

paper: fix rendering of the first tab in a line in Webkit (issue3990) This fixes issue3990 for Webkit-browsers, and also older Opera versions. Rendering in firefox is not changed.

hgweb: fix duplication for some search queries Given that N is maximum revision number in a repo, than if a revision with number N-100n or N-100n+1 (for any integer n) is found with a hgweb search, this revision is duplicated in search results.

sslutil: force SSLv3 on Python 2.6 and later (issue3905) We can't (easily) force SSL version on older Pythons, but on 2.6 and later we can force SSLv3, which is safer and widely supported. This also appears to work around a bug in IIS detailed in issue 3905.
