gud.el parses args incorrectly

gud.el parses args incorrectly

[Yuri Shtil]

It is impossible to pass quoted arguments to the gud.
For example if I say on the command line:

perl -d foo.pl one "two and three",
the ARGV in perl has two elements:
index 0 -  one
index 1 - two and three

However if I invoke perldb with the same command, I get:

index 0 - one
index 1 - "two
index 2 - and
index 3 three"

The problem, I believe is that gud-common-init in gud.el uses 
split-string which uses white spaces as delimiters and does not splits 
the command line in shell-like way as I would expect.

In the CVS repository (trunk and the Emacs 22 release branch EMACS_22_BASE)
gud-common-init no longer uses split-string and this should work.

If you can't check check out a CVS version of Emacs, then you'll need to
wait for Emacs 22.2 which was due to be released about now, although it
will probably be much later.

Alternatively you can patch Emacs 22.1 with:
