commit 313110f870c3148bcae2f9709623563df8e02fd7
Author: G. Branden Robinson <g.branden.robin...@gmail.com>

font/scripts/*: Use a better exit status.
* font/scripts/gendesc.sh:
* font/scripts/genfonts.sh: Exit with status 2, not 255, on usage error.
The latter value is not good practice per POSIX--shells use the eighth
bit of the exit status to indicate that a signal was received.
See <https://pubs.opengroup.org/onlinepubs/9799919799/utilities/\
V3_chap02.html#tag_19_08_02>.
