This actually came from the existing 'info macro'. command, I updated that.

to answer your question scope of a macro is all lines between #define
and #undef, not extending beyond the boundry of a compilation unit.

Its the wrong word though, and not what 'info definitions' does,
neither was my second patch correct.  because 'info definitions' looks
throughout a compilation unit.

Updated the docs, and the 'help' command text for 'info definitions'.
I added @cindex macros, from debug info
so it would be near the existing @cindex macros, user-defined
