Fortify against bad characters in URLs.  This also makes www print one
URI per line (which was intended in the first place).

Scripts are supposed to be launched as sub-commands of /bin/saturnin, which

Or you can still set these variables by hand.  (i.e. `FFOO_DEBUG=true saturnin-www`)

Avoids need to replace __EECC_INI__PATH

Increase readability: decrease complexity of the build function and
preserve wandering off too much against 80-char "buoy"

Make it easier to share &  sync installer code across projects from the
same family.

Too much confusing for an aesthetic feature

bbl is for Babylon

A dmenu wrapper to leverage inireader for easier work with style
configuration and to compose key/value based menus.

To simplify extraction of eecc config outside ffoo-enabled scripts
(e.g. from inside *rc file).
