Non-hash-tags

So dear Google+, kudos for finally making hash-tags link to the respective search, i.e. allowing # as a keyword marker, like Twitter.

... BUT...

... there are some pretend-hash-tags, that really aren't.  Sometimes a has is just a hash...

Like in
#define
#include
(for the geeks among us)
or #1 #2 ... (again in geek terms #\d+)

But still better to have the link to a pointless search than not have the link at all.

Kudos.
