Fix a bug in matching suffixes. Under certain circumstances the code
would access memory before the beginning of the string to match (the
suffix match starts at the end of both the string and the suffix and
proceedes to the begin until either the start of the suffix is hit
or the character does not match). This could lead to a memcpy copying
into random memory. Fix this by checking the length of the string to
match too and replacing the Lst_Find calls with LST_FOREACH loops
(last part by harti).
