…ine `/* */` comments
Code sample:
```php
/*
* Some text
*/
```
The tokenizer tokenizes this code as:
```
T_WHITESPACE T_COMMENT
T_COMMENT
T_COMMENT
```
In other words, the whitespace at the start of subsequent comment lines is tokenized as part of the `T_COMMENT`.
In effect, this meant that these lines would not throw the appropriate error, nor be fixed by this sniff.
This commit fixes that.
Includes unit tests.
Given this code: ```php wp_die( $api ); // Tab - Space - Tab - Tab ``` with tab width set to `4`, `wp_die()` would start in column 13. The sniff was currently fixing this to: ```php wp_die( $api ); // Tab - Tab - Tab - Space ``` which changed the start column to 14 and changed the "space hidden before a tab" to precision alignment. This commit fixes that and is a further iteration building onto the improvements in 1404. The above code will now be fixed as: ```php wp_die( $api ); // Tab - Tab - Tab ``` Notes: * As the tabs in whitespace at the start of `T_INLINE_HTML` and `T_COMMENT` tokens is not replaced by spaces in the `content` by the tokenizer, this has to be done within the sniff to determine what the correct length of the whitespace should be. * Basing the correction of the space-based length of the whitespace allows for fixing with higher precision. * Incidentally, this also fixes one of the metrics being recorded incorrectly. For in-depth details of the effect on the metrics of this fix, please see: https://gist.github.com/jrfnl/5e2d75894c8e60a8f314b9fcb0ad3f62 * The `tabWidth` is now set in the unit test file.

I never even noticed that the unit test for this was wrong with that mixed space/tab indent. Thanks a lot for these changes. |

You're welcome. Thanks for merging this. |

@gsherwood Greg, if you have a chance, it'd be great if you could also have a look at #1607 which basically fixes the same thing for the comments for the |

Fix the case of the moving space
This is one of the issues I came across during reviews related to the WP core code style fix effort - WordPress/WordPress-Coding-Standards#977
Given this code:
with tab width set to
4,wp_die()would start in column 13.The sniff was currently fixing this to:
which changed the start column to 14 and changed the "space hidden before a tab" to precision alignment.
This commit fixes that and is a further iteration building onto the improvements in #1404 and reverts the change in the fixes for line 22 and 24.
The above code will now be fixed as:
Notes:
* As the tabs in whitespace at the start of
T_INLINE_HTMLandT_COMMENTtokens is not replaced by spaces in thecontentby the tokenizer, this has to be done within the sniff to determine what the correct length of the whitespace should be.* Basing the correction on the space-based length of the whitespace allows for fixing with higher precision.
* Incidentally, this also fixes one of the metrics being recorded incorrectly. For in-depth details of the effect on the metrics of this fix, please see: https://gist.github.com/jrfnl/5e2d75894c8e60a8f314b9fcb0ad3f62
* The
tabWidthis now set in the unit test file.It goes without saying, that for the fixes and the metrics to be accurate, the sniff has to be run with a tab width set.
