Yeah, though the preceding paragraph contains both the general
description of the regex match, and the mention of BASH_REMATCH, so the
BASH_REMATCH angle could be a bit more explicit.
So I'd probably say that the pattern would match e.g. 'xxx aabyyy', or
'xxxbyyy' and set $BASH_REMATCH to ' aab', or 'b', respectively. And
then mention that the ^ and $ anchors could be used.
I know the usual regex behavior is to find a match anywhere within the
value, but since it's exactly the opposite of how regular pattern
matches work, it's probably worth mentioning in some way. (Though I do
think it's better to document things rather explicitly in general.)
