sendbug(1) makes terrible assumptions about your editor

[Joe Kelsey]

Sendbug is also a 'csh' script.  This causes problems if your subject
line happens to contain any special characters - $, ~, etc.  csh will
barf if you try to post a message to net.bugs.4bsd with one of these
characters in the subject line.  All distributed shell scripts should
use the Bourne shell.  csh is an absolutely horrible programming
language and should only be used for an interactive shell!!!
