Good catch!
BTW, another solution is to concatenate three messages into one.
if (stack->sym == last_sym)
fprintf(stderr,
"%s:%d:error: recursive dependency detected!\n"
"For a resolution refer to
Documentation/kbuild/kconfig-language.txt\n"
"subsection \"Kconfig recursive dependency limitations\"\n",
prop->file->name, prop->lineno);
Personally, I prefer this.
It may be a matter of taste, though.
