'gm convert' in 1.5 and 1.7

[Angelo Graziosi <angelo dot graziosi at alice dot it>]

I have noticed different results in size using 'gm convert', from JPG to 
PDF, in Cygwin 1.5 and in 1.7. For example, in Cygwin-1.5

$ gm convert -page 595x842! test.jpg test.jpg.pdf

$ ls -lrt

On Cygwin-1.7:

$ gm convert -page 595x842! test.jpg test.jpg.pdf

$ ls -lrt

So, on 1.5, 'test.jpg.pdf' has a size of 292K, instead on 1.7 it has a 
size of 1.5M!

Why this difference?

I have attached a simple test case with which one should reproduce the 
things, but this big discrepancy happens with all JPG files I have tried.

I discovered the above trying to convert many JPG files to PDF and then 
creating a single PDF with 'pdftk'. But on Cygwin 1.7 the resulting 
final PDF is very very big (image 100 JPGs...)!!


Cheers,
Angelo.
