<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There is a bug here, but your change is not fixing it.
The first line in the else block should be using "quote + 1" instead of "buf + 1" in the strchr() call. Make that change instead.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There are more problems with this code than what you have pointed out since strchr can return NULL and eol_pnt is used without checking for it.
Also shouldn't the return value be quote + 1 instead of buf + 1 ?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Indeed. It should probably be something like:
if (!(quote = strchr(buf, '\"'))) {
if ((eol_pnt = strchr(buf, '/')) || (eol_pnt = strchr(buf, '}'))) {
*eol_pnt = '\0';
}
return buf;
} else {
if ((eol_pnt = strchr(quote + 1, '\"'))) {
*eol_pnt = '\0';
}
return quote + 1;
}</pre>
