          Priority: medium
            Bug ID: 72720
          Assignee: poppler-bugs at lists.freedesktop.org
           Summary: pdfunite of a single file should not fail
          Severity: minor
    Classification: Unclassified
                OS: All
          Reporter: marc.donner at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: poppler

I have a large document (circa 1,000 pages) that I have used pdfseparate to
break into individual pages and that I am then using pdfunite to combine into
useful bundles of pages.  Some of the bundles are comprised of a single page.

I manage the bundle creation process using a set of data objects, so the basic
inner loop goes something like this:

pdfunite ${SOURCE_LIST} ${DESTINATION_FILE}

If ${SOURCE_LIST} happens to contain a single PDF file, then pdfunite whines
and refuses to work, so I've had to special case these items and make the
command be cp instead of pdfunite.

I argue that for clean closure pdfunite source.pdf dest.pdf should copy
source.pdf to dest.pdf

If the poppler community agrees that this is a valid proposal, I'd be happy to
submit a change list to implement the fix.
