'pdfseparate': Format output file name as page number with leading zeroes

Question

pdfseparate requires to specify %d as PDF-page-pattern which is replaced by the page number.

$ pdfseparate CFL_1115_ISSUU.pdf cfl-%d.pdf works. It sets separated output file names as cfl-1.pdf, cfl-2.pdf, ..., cfl-10.pdf etc.

Now I need to add leading 0 to fix the file name string length. So when I try to use formatting characters in command $ pdfseparate CFL_1115_ISSUU.pdf cfl-%04d.pdf, it gives error Syntax Error: 'cfl-%04d.pdf' must contain '%d' if more than one page should be extracted

Can anybody suggest if such formatting is possible?

On my system (Mac OS X), using the most recent version of Poppler, v0.42.0, this command works as expected:

$ pdfseparate -l 10 PDF32000_2008.pdf cfl-%04d.pdf

$ ls -l cfl-*.pdf
