The dark-bg scheme draws an explicit black background, so should also be
readable in terminals with a light background. That's been the main
show-stopper for enabling colors by default, as the 'dark' color scheme
is totally unreadable on light backgrounds and there's no way to detect
what background the terminal is actually using.
In some cases the bar width may be 1 block short due to imprecise
floating point calculations. i.e. (max_width * a) / a != max_width,
whereas (max_width * (a/a)) == max_width. Or, at least, that's what I've
observed so far.
This should really have been accepted from the start. Adding extra
elements to the top-level array might be useful for aux. data related to
the scanned files, e.g. map of seen uid/gids to names, information about
the scanned dev ids, etc. But since ncdu would throw an error on further
array elements, adding such information can't be done without breaking
compat with older versions. :(
Bumping the minor version of the file format to '2'.
The "ino" field is only interesting for hardlinks, so we can save space
by not exporting it for other entries.
The hlink count will be interesting later on when I implement tracking
of shared data between directories. It's currently ignored on import.
The "nlink" field makes the "hlnkc" field redundant, but let's keep
including that field anyway for backwards compatibility.
* Use AS_HELP_STRING instead of deprecated AC_HELP_STRING
* Use AC_OUTPUT without arguments
* Enclose AC_INIT argument in brackets
* Add automake option std-options

Reduces memory by a tiny bit. Arguably we never needed tombstones
because entries are never removed, so there shouldn't be any performance
hit there. We don't even need a 'used' flag either, considering that can
be represented by a NULL value, but I'm not really up for
implementing/modifying my own hash table.

This is a best-effort approach to save ncdu state when memory is low.
There's likely allocation in libraries that isn't being checked
(ncurses, printf).
Fixes#132 (it actually doesn't, that needs a 64bit static binary too,
but I'll get to that)
