[Swftools-common] FIX: two small format string buglets in png2swf.c and swfcombine.c

[Markus Fleck-Graffe]

"png2swf" output may become garbled:
> address@hidden:/swftools-2008-01-13-1038/src$ PATH=. png2swf
> Usage: [...]
> -s , --scale <percent>         Scale image to <percent>png2swfize.

To fix this, the literal "%" character should be quoted (as in "%%").
A quick grep found "png2swf.c" and "swfcombine.c" to be affeced.

See attached diff for fixes.

Yours,
MFG.
