It seems that IM suddenly can NOT read labels from stdin '-'!!!

I need this for IM examples as I need to pre-process backslashes and percents
while reading in labels from a file (to avoid a problem with '\n' or %c)

This in intolerable!!!



An alturnative solution is to NEVER process backslash and percent escapes when
reading labels from a file.

EG:  backslash and percent escapes are only valid from the command line
or API arguments and never in a read in from a file using '@'

This makes good sense, and if implemented then it should be documented
to make it properly defined and unchanging.


However it does have small furture expansion problem...

As -comment is not suposed to process percents or backslashes
until it actually assignes the comment meta-data to an actual image.
This make it difficult to implement  -comment '@comment.txt', unless when
reading comments from files will have to double up percents and backslashes to
ensure they are escaped properly in the unassigned comment setting.
