[SAC-HELP] merge silently fails?

Something like this was mentioned a little earlier:


I didn't see a resolution or much further discussion so 
I wanted to point out that while the older version 
of sac (00.56a) would throw an error on merging if two 
files overlapped or were less than a sample interval apart 
(ERROR 1802: Time overlap:), the newer version (100.1) 
does not spit any error (on both solaris and linux), does 
nothing with the files in memory (that I can tell), and 
doesn't halt a macro (so it just keeps on going).  It is
somewhat annoying when there is a _gap_ between two files 
ever-so-slightly less than a sample interval (like a 
millisecond), you go to merge, and nothing happens.  

Just something to look out for..
