Add support for .bzrignore
Add an initial implementation of the shortoutput option

Add a description and configuration option for --[no]shortoutout for
shorter match output; add an initial whitespace standardisation
implementation
Improve the shortoutput option with long line truncation and wrapping

Extend the --shortoutput option, by detecting the current terminal
width and ensuring that each result match doesn't take up more than
four lines - truncating as necessary.  Improve the wrapping of multiple
lines for cleaner output, and add a new --color-truncate-warn option to
highlight the truncation warning.
Add a --stats-summary option for shorter stats and info

Add a new --stats-summary option to allow output of very basic stats
(number of matches only), together with two pieces of info - case
sensitivity and symlink follow state.
