Currently, zgrep only allows a single option -e to be processed :
$ echo -e 'foo\nbar\nbaz' > test.txt
$ gzip test.txt
$ zgrep -e foo -e bar test.txt.gz
zcat: can't stat: -e: No such file or directory
zcat: can't stat: bar: No such file or directory
The attached patch allows to pass several options -e as one would do with standard grep(1) command.
