If you actually used "[:space:]*COMMENT[:space:]*" then the reason
it "worked" is because it is equivalent to just "COMMENT". The "*"
matches _zero_ or more repetitions. The "[:space:]" does not match
a whitespace character, it matches ':', 's', 'p', 'a', 'c' or 'e'.
To match a whitespace character you need "[[:space:]]".

The equivalent of your perl RE is:

" ^[[:space:]]*COMMENT[[:space:]]*=[[:spac
e:]]*\""
