Subject: 24.3; gs and filenames with percent signs

I've a file named: A13+Datasheet+-+v1.12+%282012-03-29%29.pdf
When I invoke docview (hitting return in dired), it doesn't work because
of percent signs in the file name: DocView: process pdf/ps->png changed status to exited abnormally with code 1.
Tracing docview I get:

1 -> doc-view-start-process: name="pdf/ps->png" program="gs" args=("-dSAFER" "-dNOPAUSE" "-sDEVICE=png16m" "-dTextAlphaBits=4" "-dBATCH" "-dGraphicsAlphaBits=4" "-dQUIET" "-r100" "-sOutputFile=/tmp/docview1000/A13+Datasheet+-+v1.12+%282012-03-29%29.pdf-1dc1b37082c745e206fc9363f828eb08/page-%d.png" "/home/pooh/work/srvdoc/A13+Datasheet+-+v1.12+%282012-03-29%29.pdf") callback=#[0 "\302\303\300!\304\305\306\307 \"\304\310%\210	\203\311	!\210\304\312p\313\"\207" [100 doc-view-current-timer write-region prin1-to-string nil expand-file-name "resolution.el" doc-view-current-cache-dir silently cancel-timer doc-view-display force] 6 "

(fn)"]

I see the percent signs from the filename verbatim in gs invocation, but
it's not allowed as they are (I think) getting to the printf-like
function (for %d in batches), and therefore must be presented as %%.

So the fix is easy: when preparing the invocation string for gs, change
single percent signs to double.
