If you escape a string containing spaces, what does the filename
look like?  

I experienced this xsltproc error with db2man but my refname didn't
seem to have spaces.  But the XML file looked like this:

<refnamediv><refname>mycommandname
</refname><refpurpose>...

The carriage return whitespace after the name triggered the
error.

I think db2man should be fixing this bug, however.
It should strip leading and trailing whitespace, and
translate spaces to underscores in the name.
I seriously doubt anyone using db2man wants filenames
with spaces or carriage returns, escaped or not.
