Re: [PATCH] git-fetch --tags: deal with tags with spaces in them.

Junio C Hamano [off-list ref] writes:

"git-fetch --tags" can get confused with tags with spaces in their names,
it used to use shell IFS to split the list of tags and also used curl
which insists the URL to be escaped.  Fix it so it can work with Martin's
moodle repository http://locke.catalyst.net.nz/git/moodle.git/.

The one I sent to the list was buggy and broke usual multi-head
fetches, and what I have in the proposed updates branch is a
replacement one.

We cannot still do arbitrary reference names, but at least now
we allow spaces in them.  But I am not sure if this is a good
change.

Do we in general want to support references with [^-a-zA-Z0-9.]
in them?  Most notably spaces?

The current replacement patch implies that .git/remotes/
short-cut file format now has a slight incompatible change.  You
cannot have more than one refspec on single Pull: line.  I used
to have:

	Pull: master:ko-master +pu:ko-pu maint:ko-maint

but these should now be split into multiple lines, like this:

	Pull: master:ko-master
	Pull: +pu:ko-pu
	Pull: maint:ko-maint

The latter format, one refpair per line, has always been
supported, BTW.

Opinions?
