hgweb: add websub template filter
The purpose of this new filter is to make it possible to partially replace the
functionality of the interhg extension. The idea is to be able to define regular
expression based substitutions on a new "websub" config section. hgweb will then
be able to apply these substitutions wherever the "websub" filter is used on a
template.
This first revision just adds the code necessary to load the websub expressions
and adds the websub filter, but it does not add any calls to the websub filter
itself on any of the templates. That will be done on the following revisions.
b51a8138292a introduced a regression where we would mention in the
changelog executable files added by the second parent of a merge. Test
that that doesn't happen anymore
$ "$TESTDIR/hghave" execbit || exit 80
$ hg init repo
$ cd repo
$ echo foo > foo
$ hg ci -qAm 'add foo'
$ echo bar > bar
$ chmod +x bar
$ hg ci -qAm 'add bar'
manifest of p2:
$ hg manifest
bar
foo
$ hg up -qC 0
$ echo >> foo
$ hg ci -m 'change foo'
created new head
manifest of p1:
$ hg manifest
foo
$ hg merge
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -m 'merge'
this should not mention bar:
