rebase: add option to not commit after a collapsing
This option is useful when other extensions (e.g., pbranch) want to
use rebase --collapse and append other things before committing.
This is not intended to be used from command line.

"""show progress bars for some actions
This extension uses the progress information logged by hg commands
to draw progress bars that are as informative as possible. Some progress
bars only offer indeterminate information, while others have a definite
end point.
The following settings are available::
[progress]
delay = 3 # number of seconds (float) before showing the progress bar
refresh = 0.1 # time in seconds between refreshes of the progress bar
format = topic bar number # format of the progress bar
width = <none> # if set, the maximum width of the progress information
# (that is, min(width, term width) will be used)
clear-complete = True # clear the progress bar after it's done
disable = False # if true, don't show a progress bar
Valid entries for the format field are topic, bar, number, unit, and
item. item defaults to the last 20 characters of the item, but this
can be changed by adding either ``-<num>`` which would take the last
num characters, or ``+<num>`` for the first num characters.
