[aprssig] IRLP APRS Status Script: Multiconnect Bug?

I looked at this last night and hastily edited the "aprs_status" and 
"aprs_status.conf" files on one of my low profile IRLP nodes.  Once I got it 
working as desired, I copied the files to my IRLP node 5980, which now shows 
text like "145.230MHz T136 R40m IDLE" or "145.230MHz T136 R40m REF9200" in 
the comments area.

There's a lot of nested if/else stuff in there that supports a "verbose" and 
"non-verbose mode.  Of course, the "verbose" mode easily supports the larger 
displays of traditional computer users while the "non-verbose" mode supports 
the users of the more limited displays of mobile radios.

There's also stuff that manages the display of EchoIRLP connection status. 
Unfortunately, given the format shown above, it seems that the final digit 
of some EchoLink node numbers would be truncated on some mobile displays due 
to the EL prefix plus their six-digit numeric length.  In this case, 
"145.230MHz T136 R40m EL123456" might be displayed as "145.230MHz T136 R40m 
EL12345"...  Therefore, the "EL" might be shortened to "E" to fix this? 
This would then look like "145.230MHz T136 R40m E123456" instead.

The bottom line is...  If there is no real need for the "verbose" mode, then 
a cleaner and slimmer version of the script could be put together and 
distributed.  Until a judgment is made on this, either way, I'd prefer to 
see the principal script authors make the modifications for distribution.

Steve, AA5SG
