If the message does not have to be a *single* command-line argument of
the exerr function, you can split the message in multiple arguments
and use '\' for continuation lines, e.g.:
echo "This is a very long message" \
"that does not fit in a single" \
"line of text."
This might not work if you _have_ to pass the string as a single
argument, but even in that case you can use shell substitution to wrap
the exerr() function, e.g.:
exwrap()
{
return exerr "$*"
}
exwrap "This is a very long message" \
"that does not fit in a single" \
"line of text."
