rillig a62f844ab1 p5-String-Compare-ConstantTime: fix DESCR
The comparison takes a constant amount of time, no matter whether the
strings are equal, or even the same, or different. This one sentence had
been added to DESCR out of nowhere.

This module provides one function, equals (not exported by default).
You should pass this function two strings of the same length. It will
return true if they are string-wise identical and false otherwise, just
like eq. However, comparing any two differing strings will take a fixed
amount of time, unlike eq.
NOTE: If the lengths of the strings are different, equals will return
false right away.
