bundle2: lazily iterate over bundle parts in the test

We used to create a list to know the number of parts in the bundle. This prevents
any lazy reading as planned for real usage.

The list creation is dropped. Some test output changed as debug output is
now interleaved with command output.

import os
from mercurial import ui, commands, extensions

ignore = set(['highlight', 'win32text', 'factotum'])

if os.name != 'nt':
    ignore.add('win32mbcs')

disabled = [ext for ext in extensions.disabled().keys() if ext not in ignore]

hgrc = open(os.environ["HGRCPATH"], 'w')
hgrc.write('[extensions]\n')

for ext in disabled:
    hgrc.write(ext + '=\n')

hgrc.close()

u = ui.ui()
extensions.loadall(u)

globalshort = set()
globallong = set()
for option in commands.globalopts:
    option[0] and globalshort.add(option[0])
    option[1] and globallong.add(option[1])

for cmd, entry in commands.table.iteritems():
    seenshort = globalshort.copy()
    seenlong = globallong.copy()
    for option in entry[1]:
        if (option[0] and option[0] in seenshort) or \
           (option[1] and option[1] in seenlong):
            print "command '" + cmd + "' has duplicate option " + str(option)
        seenshort.add(option[0])
        seenlong.add(option[1])
