Enhancement request: making recsel return a list of line-number matches

[Zaid Al-Jarrah]

Hi Jose,

It would be great if we could get `recsel` to return a list of line-numbers for 
the matches in a format similar to `recfix` so something along the lines of:

books.rec:52: foo: bar (maybe appending the first line of the matching record 
or the record key?)

Having that will make it easier to make the editor jump to the matches similar 
to how it does for validation errors.

Thanks.
Zaid
