Weblogo 3.7 fails to parse --title and --fineprint strings containing spaces


In Weblogo 3.4, strings accompanying --title and --fineprint options could be quoted to allow blank spaces:

$birch/pkg/weblogo-3.4/weblogo -f chitIII.pro.tcoffee.fsa --title 'two words' > test.eps

ran correctly, producing an EPS file. The specified title correctly appears in the output.

Weblogo 3.7 appears to parse quoted string arguments as separate tokens:

weblogo -f chitIII.pro.tcoffee.fsa --title 'two words' > test.eps
Usage: weblogo [options]  < sequence_data.fa > sequence_logo.eps

weblogo: error: Unparsable arguments: ['words'] 

In the latter example, the shell is calling weblogo 3.7.

I have tried double quotes, and escaping the blank character with a backslash, which give the same result.

Apparently, something in the command line parser changed after v3.4.
