url: remove , from path_chars

Related to #1972

Fixes an issue when paths have embedded comma, e.g.:

    shared/src/foo/SomeItem.m:12, shared/src/

with path_chars greedily consuming the rest of the string.

Now file path matching stops at comma. Scheme URLs are unchanged and
still using the comma.
