I thought that "overlays" were more for display properties and that
"text-properties" would be what you would want to use for storing the
line# and source file of any matches.

Are you suggesting that "M-." be used to go to the "call"? Normally,
"M-." is used to go to the definition, not a reference. Why not just
use "RET"? You could have a separate RET key binding for the who-calls
results buffer.
