debuginstall: expand the editor path before searching for it (issue4380)

The editor launches without expanding the path with commits because the shell
does that for us.

If the path isn't an executable, the expanded path is displayed, which is
probably more useful than the unexpanded path.  For example, in cmd.exe, '~'
expands to C:\Users\$user.  But it expands to C:/mingw/msys/1.0/home/$user in
MinGW.

"""hooks for integrating with the CIA.vc notification service

This is meant to be run as a changegroup or incoming hook. To
configure it, set the following options in your hgrc::

  [cia]
  # your registered CIA user name
  user = foo
  # the name of the project in CIA
  project = foo
  # the module (subproject) (optional)
  #module = foo
  # Append a diffstat to the log message (optional)
  #diffstat = False
  # Template to use for log messages (optional)
  #template = {desc}\\n{baseurl}{webroot}/rev/{node}-- {diffstat}
  # Style to use (optional)
  #style = foo
  # The URL of the CIA notification service (optional)
  # You can use mailto: URLs to send by email, e.g.
  # mailto:[e-mail]
  # Make sure to set email.from if you do this.
  #url = http://cia.vc/
  # print message instead of sending it (optional)
  #test = False
  # number of slashes to strip for url paths
  #strip = 0

  [hooks]
  # one of these:
  changegroup.cia = python:hgcia.hook
  #incoming.cia = python:hgcia.hook

  [web]
  # If you want hyperlinks (optional)
  baseurl = http://server/path/to/repo
