mailcap entry for application/pdf needs quote marks

[Steven Lucy]

The entry for application/pdf in my /etc/mailcap reads as follows:

application/pdf; evince '%s'; test=test -n "$DISPLAY"; nametemplate=%s.pdf

If I try to open an attachment called "two words.pdf" (with a space in the name) in my mail client (mutt), I get two evince windows with errors. One says "Unable to open document “file:///home/slucy/two” and the other says "Unable to open document “file:///home/slucy/words.pdf”".

If I change the mailcap line to include single quotes around the %s.pdf as below, mutt can successfully open a pdf attachment with a space in the name:

application/pdf; evince '%s'; test=test -n "$DISPLAY"; nametemplate='%s.pdf'
