[DRE-maint] Bug#972481: ruby-pygments.rb: FTBFS, tests failure (due to new pygments)

[Sandro Tosi]

Source: ruby-pygments.rb
Version: 1.2.1-1
Severity: serious
Tags: ftbfs

Hello,
pygments has been recently updated to its latest upstream release (2.7.1), and
that's causing ruby-pygments to FTBFS with tests errors:

```
  test_highlight_works_with_larger_files:               F
===============================================================================
Failure: test_highlight_works_with_larger_files(PygmentsHighlightTest)

     35:   def test_highlight_works_with_larger_files
     36:     code = P.highlight(REDIS_CODE)
     37:     assert_match 'used_memory_peak_human', code
  => 38:     assert_equal 458511, code.bytesize.to_i
     39:   end
     40:
     41:   def test_highlight_works_with_null_bytes

and

I'm not familiar enough with ruby code to be able to tell how to fix it, but
from the error message, it appears that pygments is producing a different
output than the one expected by ruby-pygments.rb testsuite.

I checked on the upstream repo and it doesnt look like anyone update the code,
nor prepared a patch, to support pygments.

Until this package is fixed, pygments and a considerable set of packages, cannot
migrate to test, so i appreciate you fixing it quickly.

Regards,
sandro
