templater: define interface for objects requiring unwraphybrid()
Prepares for introducing another hybrid-like data type. show() takes context
as an argument so a wrapper class may render its items by pre-configured
template:
def show(self, context, mapping):
return (context.expand(self._tmpl, mapping + lm) for lm in self._mappings)
#testcases bdiff xdiff
#if xdiff
#require xdiff
$ cat >> $HGRCPATH <<EOF
> [experimental]
> xdiff = true
> EOF
#endif
Test case that makes use of the weakness of patience diff algorithm
