flag has been depricated, although it still works with a warning
message, and replaced with an environment variable CLICOLOR (command
line interface colour). This could be used by other tools that
want to be able to control colour output.
In addition if the environment variable CLICOLOR_FORCE is defined
colour sequences are output irrespective of whether the output is
directed to a terminal (as long as TERM references a colour capable
terminal of course ;)

As pointed out by jhb, a more scalable solution would be preferable
when multiple applications in the base system begin linking against
libh.

The correct sequence to switch colours off is to first use 'op' if
it exists, otherwise use 'oc'. If neither of these exist then we
shouldn't be doing colour with this terminal.

unless the TERM environment variable references a valid termcap.
* Allow optional compilation of the colour support in the Makefile,
defaulting to yes. This allows us to switch it off for fixit
floppies and other mediums where space is an issue and the extra
bloat of statically linking with ncurses isn't acceptable.
* Display a warning if colour is requested with '-G' but support
for it isn't compiled in.
It is not switched on by default and must be enabled with the -G
flag. When using ls -G the output behaviour is modified with ANSI
colour sequences wrapped around filenames to help distinguish file
types. (Colours can be redefined in the LSCOLORS environment
variable as described in the manual page.)
Colour support is silently disabled (if switched on) if stdout

These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.
Additionally there were complications with the build/install-world
process. It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.
There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).
It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.
