 Well, it's more an almost complete rewrite that a diff, so perhaps
 better to evaluate it from that point of view.

 Really?  It works in dash, so how out of date is solaris's version of
posix?

 phil at poker:~/src/ssh-copy-id$ dash
 $ X=foo:
 $ echo $X
 foo:
 $ echo ${X%:}
 foo

 So, any suggestions for a portable implementation (given that I'd
rather
 assumed that if dash does it, most other shell implementations would
be
 capable too, but apparently not -- of course I've been writing shell
 stuff since the early '80s so it's a little difficult to remember what
 counts as obsolete these days).

 Ah, good point, I'd not noticed that option, but that nicely
side-steps
 the problem with there being two nc implementations with varying
options,
 so I'll definitely be using that in future -- thanks.

 Cheers, Phil.
