This change speeds up the runtime of a value-parameterized test I have which has lots of values with large strings full of unprintable characters by 2x. I profiled it and traced most of the slowness during googletest startup down to the way String::FormatHexInt was creating and destroyed a stringstream for each character in the string for each value.

This is sadly out of date now and there are merge conflicts. |
|
I rebased (actually didn't see any merge conflicts), but I can't reopen the issue because it's you who closed it (isaacs/github#583). |
|
Would you mind just doing a new PR? I want to get a clean build |
|
Done as #1225. |
