I'm not sure I see in the code were this comes from. I'd like to remove this
limitation, even if it's not a show stopper.
It is not really an implementation limitation, but a specification issue.
To specify -o foo=bar, an user can use opt:"-o foo=bar" (the quotes are
needed here because of the space between -o and foo=bar.
To specify -o "foo=bar baz", one would like to use opt:"-o "foo=bar
baz""
or use some escape for the internal quotes (escape is not supported,
IIRC).
The second issue is that I split the opt: parameter in order to fill the
@ARGV array and simulate what the shell does when somebody specify
-o "foo=bar baz" on the command line.
These issues can/should be fixed, but we should first agree on the syntax
for such cases.
BTW, do you know any Perl module that can split the command line?
(my current split(/ /, command) is really limited;)
I'll try to write the relevant documentation for this.
It may help: there are some examples in the test suite.
