Good to know.  Sometimes I think I get everything wrong.

It seems 'obvious' that internal code would be faster, but I know from 
Roman's various tests over the years that it ain't necessarily so.    
Besides, at the concept level, shells are intended as glue between 
system commands and all their internal abilities are addons.  I suppose 
when,  as you say, one replaces a multi line internal construction with 
a single line construction that calls an external prog. the mere fact of 
many lines to interpret has a penalty right there that you'd not notice 
in a compiled program.
