thanks for the patch, the actual diff looks good to me!  Just two formal
nits:

1. Your patch contains two reasonable fixes that are valuable each by
themselves; in general it's better to have single patches for single
logical changes.  That helps also for the second nit:

2. The subject line is too long:
Documentation/process/submiting-patches.rst recommends 70-75 characters
with regard to workflows and tools; splitting simplifies writing short subjects, e.g.:

  scripts/tags.sh: Prevent binary files appearing in cscope.files
  scripts/tags.sh: Add support for rust source files


Kind regards,
Nicolas
