This small change was a result of some experimentation
trading our current 'hsearch' hash scheme for 'gperf'.
I discovered that when the ':' character was a part of
each 'gperf' key, that generated search logic was more
complicated and thus slower. But without a ':', it was
a little cleaner/leaner and therefore slightly faster.
Assuming that the same trailing ':' *might* affect the
current 'hsearch' logic, to be safe we will remove it.
[ while the 'gperf' version will slightly outperform ]
[ an 'hsearch', too many ugly implementation details ]
[ were exposed which complicates future maintenance. ]
[ thus, we'll retain our current 'hsearch' approach. ]
