Issue: slevomat/coding-standard#951
SlevomatCodingStandard.Operators.NegationOperatorSpacing returns a false positive when
assigning a negative number like $a = -1 with property spacesCount set to zero.
Configuration (see phpcs.xml:
<rule ref="SlevomatCodingStandard.Operators.NegationOperatorSpacing">
<properties>
<property name="spacesCount" value="0"/>
</properties>
</rule>The output of $ ./vendor/bin/phpcs is the following:
FILE: ./slevomat-negative-operator/test.php
----------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE

2 | ERROR | [x] Expected exactly 0 space after "-", 0 found.

Which seems very strange.
Moreover, the output of $ ./vendor/bin/phpcbf is the following:
PHP Fatal error: Uncaught PHP_CodeSniffer\Exceptions\RuntimeException: Undefined offset: 6 in ./slevomat-negative-operator/vendor/slevomat/coding-standard/SlevomatCodingStandard/Sniffs/Operators/NegationOperatorSpacingSniff.php on line 70 in ./slevomat-negative-operator/vendor/squizlabs/php_codesniffer/src/Runner.php:606

Thus, it may be directly related to PHP_CodeSniffer itself.
