OBTW, NB "the trick" in the above solution--horzcat() or shorthand of
[s1 s2] where s1,s2 are character arrays will transparently "eat"
intervening blanks to create the shorter lengths automagically you're
working so hard to create..."use the (hidden) force, Luke..." :)

That's what eliminates the need for all the string parsing and just lets
it pick the last N desired characters--when were blank-filled and
right-adjusted in strvcat(), then when the concatenation of the
prepended string occurs, the spurious blanks go away on their own w/ no
additional effort.

I was simply noting elsewhere it _might_ be convenient to have a fixed
length for reporting purposes or for sorting by prepending the zeros in
place of blanks so the numeric order would be preserved and columns
would be same width, etc., etc., etc., ... Again, that would be purely
application-specific as to what is actually being done w/ them.
