In our own .gitattributes file we have attributes such as:
*.[ch] whitespace=indent,trail,space
When querying for attributes we want to be able to ask for the exact
value, i.e.
git ls-files :(attr:whitespace=indent,trail,space)
should work, but the commas are used in the attr magic to introduce
the next attr, such that this query currently fails with
fatal: Invalid pathspec magic 'trail' in ':(attr:whitespace=indent,trail,space)'
This change allows escaping characters by a backslash, such that the query
git ls-files :(attr:whitespace=indent\,trail\,space)
will match all path that have the value "indent,trail,space" for the
whitespace attribute. To accomplish this, we need to modify two places.
First `parse_long_magic` needs to not stop early upon seeing a comma or
closing paren that is escaped. As a second step we need to remove any
escaping from the attr value.
