Currently, submodule diffs can cause the diff context menu to fail
to appear because of a couple bugs in parseblobdiffline:

* it appends the submodule name to ctext_file_lines instead of
  a line number, which breaks the binary search in find_ctext_fileinfo;

* it can desynchronize ctext_file_names and ctext_file_lines
  by appending to the former but not the latter, which also breaks
  find_ctext_fileinfo.

Fix both of these.

Note: a side effect of this patch is that the context menu also
starts appearing when you right-click on submodule diffs (and not just
regular diffs). The menu is non-functional in this case, though,
since you can't run blame on submodules.
