httppeer: calculate total expected bytes correctly

User-facing error messages that handled httplib.IncompleteRead errors in
Mercurial used to look like this:

  abort: HTTP request error (incomplete response; expected 3 bytes got 1)

But the errors that are being handled underneath the UI look like this:

  IncompleteRead(1 bytes read, 3 more expected)

I.e. the error actually counts total number of expected bytes minus bytes
already received.

Before, users could see weird messages like "expected 10 bytes got 10", while
in reality httplib expected 10 _more_ bytes (20 in total).

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()

# enable demandloading to reduce startup time
