sh man page ....

I have a FBSD 9.3 desktop that supplanted a Linux FC14 desktop used for
web access, some light development, & other day-to-day tasks (i.e. my
daily driver, so to speak). I had a bunch of shell scripts written to
use Linux sh, which was in fact bash, which means it had a superset of
the arithmetic operators that traditional sh had. When I use these
scripts under sh under FBSD 9.3, they largely work, though there are
some minor differences (empty strings evaluate to zero (0) under bash,
error under sh). The man page for sh doesn't reflect some of these
compatibilities/incompatibilities, & is a bit short on its description
of arithmetic evaluations in general. It would be sweet if it were
updated to document more of the differences/similarities w/ bash, since
there a clearly a decent number of similarities, & only a few (for me)
differences. TIA ....
