Add formatting capabilities to #p4jobs.
Rather than 2 parameters as
I'd originally envisioned, formatting for a given field is now a single
string of formatting keywords, e.g.:
20words line
to limit the output to 20 words and convert linebreaks to spaces so it
all goes on one line.
This change has also been applied to #p4job, replacing the "chars" and
"normalize" parameters with a single "format" parameter that can
perform both functions (and a few more).
