Description:
The String class has an implicit constructor from size_t. This causes confusion, as it's possible to do things like

  str = 'c';

which, surprisingly, means to create a 99-character string (the ASCII value of 'c') with undefined contents.

How to repeat:
N/A

Suggested fix:
Mark the constructor in question as explicit.

Code cleanup. No changelog entry needed.
