annotate lib-src/getopt1.c @ 5596:3b1d4fa716a4
Ignore lazy docstring info, #'built-in-symbol-file; nothing built-in uses it.
2011-11-13 Aidan Kehoe <kehoea@parhasard.net>
* doc.c (Fbuilt_in_symbol_file):
Don't attempt to take file information from lazy docstring
information in compiled functions; those functions are not
built-in, and as such it's appropriate to give nil.
Fix some indentation in passing.
