I thought ^ inside [] only meant 'something special' if it was the
first character.
When ^ isn't the first character in a class it means nothing special.
That is the problem. Outside of a character class it means
start-of-string* which is special.
* or start-of-line if the m option is set, or either if both the m and
s options are set.
^ always represents the start-of-line whether the /m option is used or not.

^ Match the beginning of the line
[ snip ]
\A Match only at beginning of string
The /s option has no effect on what ^ matches.
