Space to Tab (all) inserts tabs into quoted strings

Description of the Issue

If you have a string with a lot of space in C file, the I have noticed that inside a quoted string, spaces are replaced by tab chars.

I don't remember this happening on earlier versions.
I would normally expect the tab to space to ignore quoted strings in c/c++ since the string itself has no origin.
Note: I have put the whitespace as text since the preview has whitespace suppression on.

Original line

[tab][tab]printf("Up time[space][space][space][space]: %d days, ", run);

Replaced line

[tab][tab]printf("Up time[tab][space][space][space]: %d days, ", run);

Reproduce the Space to Tab (all) command in a C or C++ file containing a quoted string with consecutive spaces. Trace the command's whitespace-conversion entry point and determine how quoted strings are handled. Done means spaces inside quoted strings remain unchanged while eligible whitespace outside them is converted, with a regression test if the test suite supports this command.
