Re: [PATCH va/i18n-even-more] rebase-interactive: trim leading whitespace from progress count

Jakub Narębski [off-list ref] writes:

On the gripping hand, the number of currently processed commits
(instructions) in an interactive rebase is a number, and arithmetic
expansion can be understood as shell equivalent of casting to integer.

I get that argument; it is a bit too cute a justification for my
taste, but the resulting code is consistent with how $total loses
the potential leading whitespace, so I'll queue it as-is.

Thanks.
