Fixes #134, a bug that showed symlinks incorrectly as broken, but only when the file was listed directly on the command-line *and* the file was in a different directory to the one exa was being run in.

I’m not sure why the old code used `String::new()`, but it doesn’t seem to affect anything.

exa doesn’t capture any failures — it’s not really worth it for such a short-lived task, and doing this results in a smaller binary.

Fixes #128.

Always rebuild with `make`

Improvements to the makefile

Because the link style and status are now both available to the function that picks the colour style, we can have it highlight broken links differently.

Fixes #131.

Provides shell completion and makes all the command-line options consistent and complete.

Fixes #150, which tracked shell completion.

The old option descriptions were all written at different times, and needed some consistency. This makes everything consistent between the help text, README, man page, and shell completions, and fixes some mistakes made when writing them.

This also adds the missing options to the man page, fixing #175.

Also, make it so the same line doesn’t get added to the .bashrc every time provisioning is run.

Turn off the git networking features

We already use MetadataExt and PermissionsExt, so it already requires a Unix system — there’s no point providing fallback implementations if it wouldn’t build on those systems anyway.

This removes openssl and makes the binary properly self-contained.

For some reason, the code that calculated the width of a cell with a path in counted the width of the path twice: once from the ANSIStrings containing it, and once more added on afterwards. This meant that the grid view thought that columns were wider than they really were, meaning fewer could be fit into a grid.

Doing this meant that the escaping functionality got used in three places, so it was extracted into a generalised function in its own module.

This is slighly slower for the case where escaped characters are displayed in the same colour as the displayable characters, which happens when listing a directory’s name when recursing. Optimise this, yeah?

This was a bug introduced by 28fce347 — it should have updated both places it does this in the function, rather than just one.
