Apache is sending strange header, 'Content-Encoding: (with' if the data being sent has escape characters.

The source code on this particular line is of httpd-2.0.52/modules/metadata/mod_mime_magic.c:

2013         for (p = names; p < names + NNAMES; p++) {
2014             if (STREQ(p->name, token)) { 
2015                 magic_rsl_puts(r, types[p->type]);
2016                 if (has_escapes)
2017                     magic_rsl_puts(r, " (with escape sequences)");
2018                 return 1; 
2019             }
2020         }

I have changed the word 'with' to another one, and httpd outputs the changed word. So definitely the location is correct. Interim fix not to send unbalanced parenthesis:
