bug-reference

This file provides minor modes for putting clickable overlays on
references to bugs.  A bug reference is text like "PR foo/29292";
this is mapped to a URL using a user-supplied format; see
`bug-reference-url-format' and `bug-reference-bug-regexp'.  More
extensive documentation is in (info "(emacs) Bug Reference").

Two minor modes are provided.  One works on any text in the buffer;
the other operates only on comments and strings.  By default, the
URL link is followed by invoking C-c RET or mouse-2.
