[FIXED JENKINS-22670] Less aggressive word breaking

Only break 30+ char words after 20 chars rather than 13+ char words after 10 chars. Goals:

* Much fewer unnecessary work breaks
* Don't break shortly before the word ends

Sample screen shots below.

**Old:** Weird unnecessary break.

**New**: Does not introduce a new line break. Example should also be pretty much the worst case for the fix in the executors list.

**Old**: Necessary break in long unbroken string to preserve the design.

**New**: Same necessary break. Still not smarter in the case of nicely breakable CamelCasing.

**Old**: Breaks words like `JavaVirtualMachines` for no good reason. More even appearance.
