Actually using regular expressions for the first

union of two character sets, or append a character to
a character set?
Say I want to replace 'disc' with 'disk', but only
when 'disc' is a complete word (don't want to change
'discuss' to 'diskuss'.) The following seems almost
right:
[^a-zA-Z])disc[^a-zA-Z]
The problem is that that doesn't match if 'disc' is at
the start or end of the string. Of course I could just
combine a few re's with |, but it seems like there should
(or might?) be a way to simply append a \A to the first
[^a-zA-Z] and a \Z to the second.
Why not
($|[\w])disc(^|[^\w])
I hope \w is really the literal for whitespace - might be something
different, see the docs.
