keyword: do not bother about detecting extension path in demo
Detecting and showing the path to a keyword extension in a
non-standard place only made sense while keyword.py was not
shipped with Mercurial.
The test output has changed because we do not have a spurious
space at eol anymore.
% inserve
A dir/c
? a
? dir/b
? hg.pid
% moving dir out
% status
! dir/c
? a
? hg.pid
Are we able to kill the service? if not, the service died on some error
