Re: Tests in Cygwin

[Don Slutz <Don.Slutz@SierraAtlantic.com>]

Here is some testing that does not require a sub-shell and does support 
options:

rhf2-1:~/tmp>foof() { local IFS='       ,+';local args="$*"; for i in 
$args; do echo i=$i; done; }
rhf2-1:~/tmp>foo1() { for i; do echo i=$i; done; }
rhf2-1:~/tmp>foo2() { for i in $*; do echo i=$i; done; }
rhf2-1:~/tmp>foo1 'a b c' d e+f g,h 'j  k'
i=a b c
i=d
i=e+f
i=g,h
i=j k
rhf2-1:~/tmp>foo2 'a b c' d e+f g,h 'j  k'
i=a
i=b
i=c
i=d
i=e+f
i=g,h
i=j
i=k
rhf2-1:~/tmp>foof 'a b c' d e+f g,h 'j  k'
i=a
i=b
i=c
i=d
i=e
i=f
i=g
i=h
i=j
i=k
rhf2-1:~/tmp>uname -a
CYGWIN_NT-5.1 rhf2-1 1.5.25(0.156/4/2) 2008-06-12 19:34 i686 Cygwin

Note: that should be IFS=$' \t+,' and $'j\tk' in case the mailer messes 
this up.   I did not use this bash special syntax.

So which should we go with? foo2() which does the original way or foof() 
which allows you to use ',' and '+', and spaces?
