I've decided not to use ls-like file name coloring for now, instead just
coloring the difference between a (regular) file and a dir.
Still looking for a good color scheme for light backgrounds.
The default shell was changed from /bin/bash to /bin/sh in commit
61a7846 ("config: Use /bin/sh as default shell and don't check for its
existence", 2015-04-05), update the documentation about this.
Check if the environment variable NCDU_SHELL is defined before the SHELL
variable is checked. This makes it possible to specify a program to
execute when 'b' is pressed. Setting SHELL to for example "mc" (Midnight
Commander) didn't work because mc already uses SHELL to execute
commands.
Key 'b' in the browse window spawns a shell in the current directoy.
We first check the $SHELL environment variable of the user for the preferred
shell interpreter. If it's not set, we fall back to the compile time
configured default shell (usually /bin/bash).

This mostly avoids the issue of getting negative sizes. It's still
possible to get a negative size after refresh or deletion, I'll get to
that in a bit.
This allows scanning stuff without initializing ncurses. Not too useful
at this point since ncdu will switch to an ncurses environment when it's
done anyway, but this will become more useful when the export-to-file
feature has been implemented.
POD is somewhat more simple and flexible. I now use ncdu.pod to generate
a nicely formatted manual page on the ncdu homepage, rather than
displaying a rendering of ncdu.1 formatted in a monospace font.
The tarball will still contain an ncdu.1, so there's no extra dependency
on pod2man. (Unless you clone from git, since ncdu.1 isn't in the repo)
