Hi,

webkit2pdf FTBFS with /bin/sh as dash due to different quoting foo in 
debian/rules:

 OP="\("
 REL=$(shell head -1 debian/changelog | cut -d ${OP} -f 2 | cut -d '-' -f 1)

 […]

       debian/rules override_dh_auto_configure
   make[1]: Entering directory '[…]/webkit2pdf-0.3'
   cut: the delimiter must be a single character
   Try 'cut --help' for more information.
   pod2man -d 2016-05-19 -r  -c "" debian/webkit2pdf.pod debian/webkit2pdf.1

"Hangs" there, presumably waiting on stdin due to lack of argument to "-r".
I'm guessing under bash, the "(" is quoted/expanded, etc. etc.

Patch attached that simply uses a more reliable way to parse the version
number, which is a good idea anyway.


Regards,
