to have either one more or one less > at the front. A web site tells me that 
the regexps to use are:

1,$s/^>*From />&/


1,$s/^>(>*From )/\1/

respectively (there is a single space after "From"). So, if my text string is 
in $line, I ought to be able to do something like:

$line = preg_replace ($pattern, $replacement, $line);

But, since all regexps are to me, like TECO commands, no better than 
line-noise, how do I make up $pattern and $replacement from the proffered
