This upgrades the versions of everything, including upgrading almost all outdated dependencies.
• number_prefix had some backwards-incompatible changes. It now feels more Rustful, and spells "Mebi" correctly.
• term_grid stopped working when I upgraded it, worryingly, so I reverted it back.
Using --octal_permissions will insert another column before the existing
permissions where permissions are encoded using octal values as
requested in #316
Also adjust the selection of the colour depending on the scale used.
* With decimal prefixes colours change on powers of 1000.
* With binary or no prefixes colours change on powers of 1024.
Fixes#288, but more-or-less as a side-effect.
The “mi” key in LS_COLORS was meant to be used for a missing link path, but it wasn’t really used like that. There was also a bug where control characters in a broken symlink’s path were assumed to be underlined, because that’s what happened in the default colour scheme, but this assumption doesn’t hold when colours were disabled.
The solution to these was not to introduce another configurable colour code, but to start using _overlays_ to alter a bunch of colours at once. The “mi” code will have to be added back later.
This adds support for the EXA_COLORS environment variable, and defines a bunch of exa-specific two-letter codes that I pretty much made up arbitrarily that control parts of the interface.
Fixes#160, which I didn’t expect to actually fix this release cycle, but it unexpectedly became easy to do!
