topic: improve UX by using pager only when we should
Before this patch we were using pager in every case of topic command,
either it is setting up a new topic or clearing the active topic.
After this patch it will not use pager in following commands:
$ hg topic [TOPIC] -r [rev]
$ hg topic --clear
import hghave
@hghave.check("docgraph-ext", "Extension to generate graph from repository")
def docgraph():
try:
import hgext.docgraph
hgext.docgraph.cmdtable # trigger import
except ImportError:
try:
import hgext3rd.docgraph
hgext3rd.docgraph.cmdtable # trigger import
except ImportError:
return False
return True
