I just did `more fastgrep.c' and found following piece of code.  The
usage of wflag is an obvious regression from OpenBSD code.

|       if (fg->len >= 14 &&
|           strncmp(pat + (fg->bol ? 1 : 0), "[[:<:]]", 7) == 0 &&
|           strncmp(pat + (fg->bol ? 1 : 0) + fg->len - 7, "[[:>:]]", 7) == 0) {
|               fg->len -= 14;
|               /* Word boundary is handled separately in util.c */
|               wflag = true;
|       }
|
|       /*
|        * Copy pattern minus '^' and '$' characters as well as word
|        * match character classes at the beginning and ending of the
|        * string respectively.
|        */
|       fg->pattern = grep_malloc(fg->len + 1);
|       strlcpy((char *)fg->pattern, pat + (bol ? 1 : 0) + wflag,
|           fg->len + 1);
