Severity: normal
File: /usr/share/man/man1/jpegtran.1.gz

Mention why -rotate 90 causes one's jpeg file size to go from 90 Kb
to 100 Kb.

I didn't check but this means 3 more rotations back to vertical will
make the file 130 Kb. Lossless maybe, but not gainless.

Mention what is going on on the man page.

-trim didn't help.

convert -rotate 90 kept the same file size. Not sure if it is lossless.

Wait: I see, one is supposed to see the cjpeg man page to learn
about  -optimize.

OK but still mention factors infuencing filesize right there on this man page.
