Error: chomp on nil

[Taknok]

What happend

The following error is sometimes returned and the tool crash:

private method 'chomp' called for nil:NilClass (NoMethodError)

Why

This is triggered by this line:

svn2git/lib/svn2git/migration.rb

Line 405 in 6dac85a

loop { @stdin_queue << $stdin.gets.chomp }

gets may return a string or nil according to the documentation: https://ruby-doc.org/core-3.1.1/Kernel.html#method-i-gets
nil does not have a chomp method and trigger the error (with a crash).
