Kind of diverging from the topic at hand, but:
sed 's/ /:/'
to do the conversion myself. (Note that sed will only perform one
replacement per line by default.)
You can do global replacement like so:
sed 's/ /:/g'
All the best,

Sadly the sed scripts posted to the list do not work on the output of
the OS X strings program. This version of strings includes leading
zeros in the offset value. Thus, an output line from OS X strings like
0 %PDF-1.2
gets converted to
: 0 %PDF-1.2
instead of the desired
0:%PDF-1.2
Hence the optional whitespace before the offset in the Perl regex.

Try this one on for size (tested against strings(1) in OSX 10.5.8):
sed 's/ *\([0-9]\{1,\}\) */\1:/'
Replaces the first instance of "[optional spaces]<1 or more
numbers>[optional spaces]" with "<found number>:". Should be a
little
cleaner and quicker than firing up Perl, and if you'll notice it's
essentially the same regex you're running, if modified for sed
semantics.

Hi RB,
The sed command works like a charm, thank you!
I learned Perl before sed, so the latter is not always my first
instinct.
